A lot of folks here are saying that the TT ban had nothing to do with free speech. A couple of indirect rhetorical questions that might be relevant to help illuminate opinions about TT:
1. If there were a single newspaper (in the pre-internet era) that developed and printed a lot of reporting with a particular political outlook and was the home of many columnists known for being the premier thinkers with that outlook, and a law were passed that had nothing to do with the content but had the effect of shutting down that paper, and only that paper, would this be a speech issue?
2. If a political rally were assembling to petition for redress of their grievances, and a law were passed that told them they could say what they wanted but the rally was only allowed to occur in a specific field 30 miles outside the city and 3 miles from the nearest paved road, would this be a speech issue?
3. Given that deadtree-books-in-physical-libraries are not the primary point of reference for most people anymore, if you wanted to block access to certain kinds of information and/or make a statement about doing so, what action would you take in the 21st century to do the equivalent of a book burning? And would this be a speech issue?
There are obvious and easy things you can point out about how the TT law is different from each of those three scenarios, don't @ me about that. But it seems to me that most people who are serious (or, publicly serious, which is a little different) about supporting the TT ban give reasons for it that would be inconsistent with their answers to one or more of those three questions.
That's a pretty substantial difference.
(2) Also doesn't match the situation, there is no requirement that TikTok restrict the reach or audience of their content in any way AFAIK.
(3) The situation is more akin to "foreign government owns the local library, and can decide based on the identity of the person walking in which books the person is allowed to see and check out" - seems obviously problematic at least /if they do that/
