I’d guess that’s sooner than needed and that means more waste

I’m sorry you are getting downvoted, because technically you are right. TikTok will never claim to aim at children or advertise as such because they know they can’t provide a safe environment and will open themselves up to lawsuits.

I don’t think trying to control is the best way of looking at it. There’s a hive mind about the fediverse that has a purpose, that wants to protect it as part of the identity of it. So a collective of instances banding together to keep that intact seems right up its alley.
