It's hard for me to interpret all of this ill will toward TikTok as anything but sour grapes from Facebook, YouTube, and Twitter (cough Vine) for getting fairly out-competed by an app that's way more fun and innovative than any of their social efforts have achieved in over a decade.
Not just from them. I really despise the short video format and the culture that surrounds so I can't take an unbiased view on this. I'm sure there are many others like me.
