Sonos has warned customers who bought speakers five or more years ago that it will no longer provide software updates to their property, and that they will cease to operate in systems that include newer equipment, and will have to be separated on its own subnet. Read the rest

Abbott Labs makes a continuous glucose monitor -- used by people with diabetes to monitor their blood-sugar levels -- called (ironically, as you'll see below) the Freestyle Libre. Read the rest

"Activation Lock" is a tool that uses Apple's trusted computing hardware to render systems inoperable if you don't have a login/password; nominally, this is used for theft-deterrence, but when Apple product owners fail to disable Activation Lock when they dispose of their equipment, it becomes effectively impossible to refurbish or repair, dooming it to become e-waste.

How can a single, ill-conceived law wreak havoc in so many ways? It prevents you from making remix videos. It blocks computer security research. It keeps those with print disabilities from reading ebooks. It makes it illegal to repair people's cars. It makes it harder to compete with tech companies by designing interoperable products. It's even been used in an attempt to block third-party ink cartridges for printers. Read the rest

Last month, a developer called Axi0mx released an Iphone crack called Checkm8, which attacks a defect in the Ios bootrom, a low-level piece of code that has not been successfully attacked since 2010. The bootrom is read-only, making its defects effectively unpatchable, short of removing the chip and swapping it for one with more robust code (the attack also works on version 1, 2 and 3 Apple Watches).

A bit of good news for pro-democracy protesters in Hong Kong, and the app developers trying to help them not get injured or killed by police. Read the rest

“Interoperability” is the act of making a new product or service work with an existing product or service: modern civilization depends on the standards and practices that allow you to put any dish into a dishwasher or any USB charger into any car’s cigarette lighter. Read the rest

Hkmap Live is a crowdsourced app that uses reports from a Telegram group to track the locations of protesters, police, and traffic, as well as the use of antipersonnel weapons like tear gas, mass arrests of people wearing t-shirts associated with the protest movement, and mass transit closures in proximity to demonstrations (it's a bit like Sukey, the British anti-kettling app).

Hasbro's got a new foam dart gun, the $50 Nerf Ultra One blaster, and to make sure that owners of this toy arrange their affairs to the benefit of Hasbro's shareholders, the company has engineered a digital rights management system that detects and refuses to fire third-party darts, which sell by the hundreds for just a few bucks (the official darts are $10 for 20), which means that party organizers running Nerf wars will have to scale back their ambitions or shell out like crazy.

In my latest podcast (MP3), I read my new Locus column, DRM Broke Its Promise, which recalls the days when digital rights management was pitched to us as a way to enable exciting new markets where we'd all save big by only buying the rights we needed (like the low-cost right to read a book for an hour-long plane ride), but instead (unsurprisingly) everything got more expensive and less capable.

The established religion of markets once told us that we must abandon the idea of owning things, that this was an old fashioned idea from the world of grubby atoms. In the futuristic digital realm, no one would own things, we would only license them, and thus be relieved of the terrible burden of ownership. They were telling the truth. We don’t own things anymore. This summer, Microsoft shut down its ebook store, and in so doing, deactivated its DRM servers, rendering every book the company had sold inert, unreadable. To make up for this, Microsoft sent refunds to the custom­ers it could find, but obviously this is a poor replacement for the books themselves. When I was a bookseller in Toronto, noth­ing that happened would ever result in me breaking into your house to take back the books I’d sold you, and if I did, the fact that I left you a refund wouldn’t have made up for the theft. Not all the books Microsoft is confiscating are even for sale any lon­ger, and some of the people whose books they’re stealing made extensive annotations that will go up in smoke.

In my latest podcast (MP3), I read my essay "A Cycle of Renewal, Broken: How Big Tech and Big Media Abuse Copyright Law to Slay Competition", published today on EFF's Deeplinks; it's the latest in my ongoing series of case-studies of "adversarial interoperability," where new services unseated the dominant companies by finding ways to plug into existing products against those products' manufacturers. This week's installment recounts the history of cable TV, and explains how the legal system in place when cable was born was subsequently extinguished (with the help of the cable companies who benefitted from it!) meaning that no one can do to cable what cable once did to broadcasters.

As long we've had electronic mass media, audiences and creators have benefited from periods of technological upheaval that force old gatekeepers to compete with brash newcomers with new ideas about what constitutes acceptable culture and art. Those newcomers eventually became gatekeepers themselves, who then faced their own crop of revolutionaries. But today, the cycle is broken: as media, telecoms, and tech have all grown concentrated, the markets have become winner-take-all clashes among titans who seek to dominate our culture, our discourse and our communications.

Last summer, we published a comprehensive look at the ways that Facebook could and should open up its data so that users could control their experience on the service, and to make it easier for competing services to thrive. Read the rest

In my latest podcast (MP3), I read my essay "Interoperability and Privacy: Squaring the Circle, published today on EFF's Deeplinks; it's another in the series of "adversarial interoperability" explainers, this one focused on how privacy and adversarial interoperability relate to each other. Read the rest

When Congress legalized phone unlocking in 2014, they added a bunch of carve-outs that let phone companies veto your attempt to unlock your phone, with the big one being that you couldn't unlock your phone while you were still in a contract that provided it to you at a reduced price. Read the rest

In my latest podcast (MP3), I read my essay "IBM PC Compatible": how adversarial interoperability saved PCs from monopolization, published today on EFF's Deeplinks; it's another installment in my series about "adversarial interoperability," and the role it has historically played in keeping tech open and competitive. This time, I relate the origin story of the "PC compatible" computer, with help from Tom Jennings (inventor of FidoNet!) who played a key role in the story. Read the rest

Adversarial interoperability is what happens when someone makes a new product or service that works with a dominant product or service, against the wishes of the dominant business. Read the rest
