Thing is, the time for net-zero has passed, did you hear that whooshing sound?
To pull back from the brink, what is needed is net-negative, which ain't happening without capture (alongside massive reduction in emissions), economics be damned, it's an existential threat, it's about survival. Could be as simple as massive reforestation, could be fusion generators pulling CO2 out of the air, will probably be many different things, but learning what works, as soon as possible, is imperative.
I run a gluetun docker (actually two, one local and one through Singapore) clientside which is generally regarded as pretty damn bulletproof kill switch wise. The arr stack etc uses this network exclusively. This means I can use foxyproxy to switch my browser up on the fly, bind things to tun0/tun1 etc, and still have direct connections as needed, it's pretty slick.
