Ask HN: What may be happen if I break license of open source project?

The ghosts of Richard Stallman, Eric S. Raymond, and Bruce Perens will come and visit you while you're sleeping, and fly you around the world, showing you all the evil that has befallen the world as a result of your infraction.

Or you could just get sued. Or publicly shamed in a very visible way.

Or maybe nothing at all. It's really hard to say.

But don't do it. If you can't accept the terms of the license, don't use the software. This isn't rocket science.

SCO will happen my friend. I'm just kidding of course but therein lies a wealth of information about the many ways it could come back to bite you. https://en.wikipedia.org/wiki/SCO%E2%80%93Linux_disputes
