I could see it becoming big with pc gamers for how much you can tweak the OS itself to eek out as much performance as you can get. They also tend to want to personalize their PCs a lot and with linux they'd have a whole new level to that with the customizability of the desktop experience itself.

It doesn't spy on you. It gives you freedom of choice when it comes to desktop environment, and what software you run. It's not developed by anti-competitive tech giants.
