As America's phone and cable companies roll out their "six strikes" plans (which they voluntarily adopted in cooperation with the big film companies), it's becoming clear that operating a public Internet hotspot is going to be nearly impossible. Anyone operating a hotspot will quickly find that it can no longer access popular sites like YouTube and Facebook, because random users have attracted unsubstantiated copyright complaints from the entertainment industry. Verizon (and possibly others) have made it clear that this will apply to businesses as well as individuals, meaning that firms will have to spy on all the traffic of all their users, all the time, and heavily censor their use of the Internet in order to prevent them from attracting these complaints.
It's not much of a stretch to see why the carriers would like this: every time you use a hotspot instead of using your phone or device's metered data-plan, they lose revenue.
Also, as the strikes get higher, there are two things to be aware of: ISPs are then more likely to hand over info to the copyright holders, meaning that it could still lead to copyright holders directly suing. That is, the "mitigation" factors are not, in any way, the sum total of the possible consequences for those accused. On top of that, we still fully expect that at least some copyright holders are planning to insist that ISPs who are aware of subscribers with multiple "strikes" are required under law to terminate their accounts. At least the RIAA has indicated that this is its interpretation of the DMCA's clause that requires service providers to have a "termination policy" for "repeat infringers." So it's quite likely that even if the ISPs have no official plan to kick people off the internet entirely under the plan, some copyright holders will still push for exactly that kind of end result.
