This is something that the amazing Naomi Wu brought up for years before, and was ordered to stop publishing by the local government. It was about the same thing. It's sometimes misrepresented as being about Signal, but her point was: There's no point in using a secure messaging app like Signal if your keyboard (IME) leaks everything you write! So she was making the exact same point as in this article.
I really miss her content. π’
Good. I hope people will move away from it soon. I hate Discord for banning third-party clients and datamining my system for installed apps. So I've never really used it.
It does mean I'm excluded from some FOSS projects' support like Home Assistant but to hell with that :P
