I'm having a hard time figuring out what you're even talking about tbh. Just.......gestures to everything? The only real things you mentioned are "one privacy-overreach followed by another", and "some random organic act-of-god".
Can you be more specific about what exactly you're talking about?
Nope. If you use docker containers on windows or mac, they're running using an abstraction layer. Docker is the native app, but what's running inside them isn't. At best they are nearly identical in performance with negligible hit to performance, but as soon as you use things like port forwarding the performance takes a hit.
