When those measures are circumvented, Nintendo and third-party game developers suffer tremendous harm because, for example, individuals can then use the emulator to play pirated games.
Those pesky pirates are playing games available exclusively on the second-hand market on consoles we're not selling anymore!

You can change the DE (desktop environment) as you like but I really like Budgie from Solus. My daily driver is Plasma and find myself on openSUSE Tumbleweed. It's by far the most crash-free and freeze-free experience I've had while using Plasma. Note: Installing Nvidia Drivers is at your own risk, though.
