“own rules”. I didn’t invent copyright.
Yeah you really don’t seem to understand how any of that works.
If you use a platform and that platform specifically states that they have rights to use your “work” if you post there, then they can. For one, if they couldn’t, then they wouldn’t be able to display your comment to begin with.
They can add in their terms of usage that they are allowed to do more with your work, like analyze it for personalized ads, for example.
You adding your license thingie in your message is a cute way to try to say “no you can’t!” But yeeaaaahhh, that’s not how anything works. You can’t simply make a license that invalidates the terms of service of a website. It’s literally the same nonsense that those sovereign citizen idiots try to pull with police and government (and always fail in hilarious ways)
