How have I regretted purchasing Blu-Rays in the past. They require an update to the drive firmware, they require their own GPU driver version, they require an update to the player software, and they try to sneak spyware onto my PC anyway. It is almost impossible to legally watch an authentic blu-ray on a Windows PC.
Similarly, how have I regretted allowing my TV to connect to the internet. The first thing that happened was that it started shoving ads into my face. So I did a factory reset and disconnected it. Now, Netflix and Prime TV are unusable. Plus the YouTube app never managed to play back 4K videos on a 4K TV without crashing.
I don't quite know why they hate me so much, but whenever I try to be nice to movie companies and purchase their stuff, they treat me like shit. And DRM is their legal whip to fuck me over. Blu-Ray? doesn't work. DRM. Offline iTunes? doesn't work in 4K. DRM. Prime TV? mandatory internet for DRM. Then ads. Netflix? mandatory internet for DRM. Then ads.
On the other hand, an mkv file on a USB stick "just works", has exceptional audio and video quality, doesn't buffer, and I can skip all the ads.
