Twitter restricts Substack links

Twitterers are complaining that posting links to their Substack newsletters and blog posts results in tweets that can't be liked, retweeted or replied to, even by themselves. Substack itself complained in a statement:

We're disappointed that Twitter has chosen to restrict writers' ability to share their work. Writers deserve the freedom to share links to Substack or anywhere else. This abrupt change is a reminder of why writers deserve a model that puts them in charge, that rewards great work with money, and that protects the free press and free speech. Their livelihoods should not be tied to platforms where they don't own their relationship with their audience, and where the rules can change on a whim.

"But Elon promised free speech":

"It appears that Musk is making decisions based on his own financial interests and petty grievances — even if it makes Twitter objectively worse for users," Judd Legum, author of Popular Information, a politics-focused newsletter with more than 240,000 subscribers, says in an email to The Verge. "If this continues, it's hard to justify continuing to invest my time creating content on Twitter."
