I’m ok with you, he doesn’t want other people to use his work but he allows himself to do so because he is apparently more important than others. Great.

Sorry but lol. You’re crazy my god. I’m sure you don’t event understand half of this list. Spotify and Netflix are DRM protected and? I think you are not living in the real world. All their contents are available elsewhere for free.
Blockchain is just a bullshit word and not even a proper protection technique.
License keys are useless and bypassed in minutes once the software is popular.
Video games are probably the best-protected things and even there, Denuvo is almost the only somewhat solid player. But it’s a huge machine that costs a lot of money and has huge drawback and even big studios don’t use it that much. And it doesn’t even work all the time xD
