Exactly, it gives the illusion of content ownership for the creator, but the biggest beneficiary is platform/studio..etc

Upload your content to proprietary platforms, they claim ownership over it so they can go after anyone who uses it without your consent, sounds good on paper, until you realize it's all part of their ad driven business plan.

a good example of this is Facebook and IG (useless) share button, what's the point of sharing from these platforms if people have to sign up to view that content.. so what you notice is that the most vocal platforms about content ownership are the most locked down ones, the ones that hold their creators and consumers as hostages, and the irony is that these platforms can license your content to third parties whenever they wish

on Spotify this recorded segment plays after (or before) random songs: "ads help us pay the artist you love.." 🙄😒.. seriously you pay artists a fraction of cent for each ad which requires surveillance for the ad machine to work.. it's a system that doesn't care about how much stuff it breaks as long as there's money to be made, (for the people who own the platform, not the creators of course)

copyleft solves this, it frees information while giving creators an ethical way of monetizing their work. (I'll write a post about it)
