> It seems weird to me that Twitter is the only one people seem to be up in arms about
They're the only one releasing internal files. If others did, like Facebook or Youtube, or Fox if you really want (but that would be a strange choice) do you think we'd only be up in arms about Twitter or do you think you might hear "Now it's Twitter and Facebook!" Regardless, I've seen plenty of people pointing out that this probably went on in many places, it's just harder to get worked up about a negative, implausible as it is.
> Twitter didn’t even really block most things, they just added a small banner alongside some statements that amount to being a reminder to check your sources.
That's simply not true and makes it seem like you haven't read the article or the associated Twitter thread. I'm not going to provide the quotes because you should've read the article instead of providing an untrue anecdote, and you can click the link above.
It's also not relevant whether they blocked "most things", what matters is that they blocked true things, things provided by notable experts, and that they were blocked because they inconvenienced the powers that be or dissented from the official line.
