i think you need to do more to justify that this is viewpoint discrimination, “tiktok” does not appear to me to be a viewpoint. i think you have a stronger argument with saying it is the broader content based discrimination, though. however id still question if that’s true with respect to corporations hosting eachothers services. id say you have a stronger argument than viewpoint discrimination by saying it violates the first ammendment of the users of tiktok, personally, though the courts might disagree. i dont really care about apple and google’s right to free speech at anywhere near the level of individual humans.
this is a much better response to the arguments in general, yes, good.
