It's not only media companies with DRM
IoT integrations like Alexa come with numerous security requirements that are often good ideas in theory but lead to hacky workarounds to meet certification requirements
My point is, it (and Youtube) killed piracy for the most part when it comes to music. Trading CDs full of mp3s used to be a sport in school a decade or two ago, these days why would anyone even want to invest the time when Spotify has everything anyway at a price point school kids can afford it?
Netflix used to become the same thing for movies, but the greed of studios killed it and now it's more expensive to have the large stream services than cable TV.
I'm not sure that's really a memo I'd like them to get. We don't need more subscription services where you don't get to own you content and everything can be taken away at any time.
It also doesn't cause (intentional) incompatibility problems like HDMI DRM does.
Of course then you have MS which basically just turned XBox into a cheap but totally locked down gaming PC (since there are very few Xbox exclusives these days).
