Sony has committed official drivers for PS5 controller under Linux. The experience with it is really plug-and-play... just that you don't plug it in.
Some people don't like the layout others prefer it. I use it myself on my Linux computer. So I wanted to name this option here.
IDK is the average TikTok user really installing VPN software on it's phone? And if something is banned in a country companies are far less likely to put in effort in it.
So even if people can still use it, technically, TikTok lifes of selling scam shit to people... If you have the skills to install a VPN your probably also not falling for that stuff.
I actually see that as a win. TikTok is not a platform for political discussion or private communication (by design) so I don't hate the idea of it getting banned.
