WordPress is copyleft (GPL), and copyleft is open source. And these are the consequences and indeed the intentions of open source. There's no "ripping off", this is what Open Source licenses permit. If contributors didn't want this to be possible, they shouldn't have licensed their software this way. (Of course, WordPress itself is a fork of a GPL project, so didn't have the option, and you could equally say it's "ripping off" that project. But we don't. Because it's open source. And that's how it works.)
