Many companies are so out of it they don't even let you stream content to browsers running on Linux distros. Even Amazon owned Audible just fixed that issue a few months ago.

I very much prefer DRM over having everything I do on the internet to be monitored.

Well, I find it hard to compare those two. I mean, yes, if DRM works I have no issues with it either, but sadly it causes a lot of issues where none should be (e.g. Hardware DVD Players not being able to play certain DVDs, Spotify Web player having issues because it doesn't overcome its own protection, not being allowed to view 'your content' on your favorite device, not being able to save 'your music' to your old mp3 player) and one of the biggest issues is that you aren't allowed to do anything against it.

Tracking is a completely different beast. They take what they can get, but you can fight back. My biggest concern is that they (Google,Facebook) gain so much influence that they can change the political opinions via Ads. So yes, tracking and advertising can be a lot more harmful, but at least you can kinda opt-out (e.g. use curl to browser the internet ;-).

What exactly do you mean by 'monitored'? Of course sites you visit on the internet know you visited them, just like shops you visit IRL know you visited them. But it's not anyone is actually monitoring you or any other user personally. The worst that happens is some algorithms change your ads.
