One thing of note is that them collecting everything on the platform doesn't really hit me in the same way as facebook doing. Somehow tho tiktok gets more hate.

Facebook being a more traditional social media has people dropping info and stuff about their plain personal life whilst tiktok is more of a content platform like youtube.

Also unlike facebook and google tiktok has a thougher time following people all around the internet which is probably by far the biggest invasion of privacy.
