I don't know the legals in detail, but I cant imagine that GPL would do something about how you use it in your home? How is that enforceable?

Again don't now the legals but I think in practical terms this affects companies trying to own a project.

> using something in a way you don't like

You're mischaracterizing what I'm saying. For one thing you're talking about "someone" when I'm taking about "someone with power". Copyleft isn't about two people, one gaining power over the other. It's about lots of people with no power protecting themselves again one entity with a lot of power to impose themselves.

> Do you have an example of that happening?

Are you new to HN? Every month there's news of projects trying to arrest power contributors using various shenanigans. Copyleft protects against a class of such attacks.

Eg Oracle and open office, red hat and centos.

Edit this is literally on HN right. Is this your first day here or something? https://old.reddit.com/r/linux/comments/1puojsr/the_device_t...
