It might not be the thing driving people to switch, but I'd be hesitant to claim that Desktop Linux is any worse than the competition. Like, I don't have the exposure to comment on Apple's products, but Windows is no better than XFCE, GNOME, MATE, or KDE these days, Android is a toy, and ChromeOS isn't better. Like... I know this is weak praise; Windows versions after 7 got worse as they fragmented (have they re-merged the control panels yet?), Android was born a mobile OS, and ChromeOS was always meant to be cut-down, but the result is that the playing field is level.
