Anybody who isn't trying to ban it as they try to ban TikTok, unless they see a material difference in the behavior of the applications other than hypernationalism.
Ban both for kids. Double ban Instagram. If nobody has planted a flag in your moral center, you'll rarely find a reason to mention TikTok by name when talking about the manipulation and surveillance that social media decided it wants to be.
I have no love for facebook, but if we're talking about protecting kids from exploitative social media, it's probably beneficial to focus on platforms they actually use.
