Oh, my idea isnt perfect. Not even close haha
It would cause platforms to become subscription based or be backed by large companies for their own profit ( see linux, github, and every open source, non profit organisation backed and/or managed by bigger companies ). No person on the internet would agree with that and its a hard bullet to bite.

Its just that from a eu citizen standpoint, this ban solves nothing for them. Its like giving the keys to everything for some bad guy to some other bad guy that both want to be above you.

And american citizens also dont benefit jack shit from this. If not, makes it worse for them as the tiktok data can now be used to make their lives worse, easier.

I will say that i agree something is better than nothing and something had to be done, dont get me wrong. I just think it was a half ass, political war bullshit choice they made with the resources they had that solves nothing besides "oh no, china be harvesting more data than us. Quick! Respond!".
Meanwhile some eu countries took on a grander scale and banned tik tok apps on government devices, which does a better job than this imho ( source : https://edition.cnn.com/2023/02/28/tech/tiktok-eu-ban-intl-hnk/index.html ) AND they did it last year :p

There were also ideas pitched around to extend this to all social media apps, but i assume that was shut down due to obvious reasons.
