I agree with not overly fanboying, but “they might stop support” can literally happen with any platform. If AMD stops open source support, they’re in the same boat as NVIDIA but with a leg up from having all the history an experience from the time with support.
Your favorite distro could go out of support and have the project closed tomorrow, just like Windows 10 reaching EoL. Except someone else can fork that distro and pick up the mantle to continue the project.
That game that you really want to play on Linux might suddenly choose to implement an anti-cheat or DRM that isn’t compatible with Linux, or a different game might choose to remove that block and it suddenly opens up for the Linux community.
Windows Registry
I had recurring issues with registering Bluetooth devices, where they would pair initially but refuse to connect again after a reboot. I couldn’t remove the device from saved connections, and registry edits wouldn’t save or persist. I’d have to completely uninstall the driver, change the registry, and reinstall the drivers, with restarts between each step, to get it to work for 1-2 days.
Now, having to troubleshoot isn’t what turned me away from Windows to Linux. I knew I would run into that plenty on Linux as well, but I came to hate the registry. If I was going to have to go through all this trouble to get things to work, I might as well do it on a system I had more control over. I had worked with different distros on VMs and dual booting before, so when I built a new system, I just skipped Windows entirely.
