The screen is yours, the content displayed is not. Same reason you can "buy" a movie, game, audio, ebook and have it disappear overnight. Same reason your security camera, car, oven may suddenly cease to work if the company shuts down their servers. Do we support it? You do because you paid for it.

Sure but traditionally this was a purely legal mechanism. There was no technological measure preventing you from copying a book, only a legal threat looming over _what_ you do with the copy.
Nowadays we have this very corporate-positive situation where copyright holders have their cake by embedding DRM and eat it too by leveraging the DMCA to prevent DRM circumventions. So you can be screwed even if you only want to take private screenshots, make backups, or exercise fair use.
When I try to play something on youtube that has the DRM bit turned on (or anything on netflix), my whole entire screen turns off. Not only can I not see the content, I also can't use half of my screen for other purposes while I play the content on the other half.
