Productivity: once your Linux machine does what you want, it does what you want. It doesn’t ask if you’re sure you don’t want ai cloud storage telemetrics shoved up your hinders every 2 clicks.

I have ADHD: I get shit done on Linux. You can turn off whatever you want and it stays off. Windows (especially 11) is a bs distraction minefield by default. And it’ll actively work against you to keep it that way.
