Until one day I got so frustrated with constant settings resets, reboots at the worst times for software updates that fail, highjacking my pc after every update for a guided tour of the latest things Microsoft decided to break, and telemetry that can only be disabled with an obscure registry hack that changes every few months, I just couldn't anymore.
Linux has been good enough as a daily driver for a while now, but even with proton I don't know if the pull factors towards Linux will ever be strong enough for most people. For me though the push factors away from Microsoft had gotten so strong I couldn't take it anymore.
