I bit of anger or at least disappointment in your post. However, "The fact that everyone has a device with a bunch of proprietary backdoors that they don't have root on and that serves as a single lynchpin through which their life can be ruined is the most fundamental destruction of personal computer and identity security that's ever been realized" is completely true.
You should be angry at people who try to hack your computer with the express intent of spying on you or controlling your behavior. I am angry that people will waste my time trying to defend this behavior to me, whether it's about phones, smarthomes, or video games
Also, the thing where people think being angry makes you automatically wrong has gotta be a holdover from lead paint. I truly can't believe people are that stupid naturally
Because I can't fit hundreds of tb of stuff on every endpoint and don't like having to manage either adding or removing dirs from Syncthing or moving things in/out from preexisting sync dirs. IME Syncthing is also less performant on hundred-gb scale copies.
It all happens in the bacground. You define which folders to sync and additionally you can sync with as many devices you wish (e.g. a backup in your own server).
