Victim blaming.
It's becoming very clear that you should no longer license your hard work like this, or vultures like Amazon or WPE pick off all the value you created.
Sorry for our collective mistake. It's a hard lesson to learn for Matt and co., but the rest of the internet is learning not to enable this.
You'll probably get away with doing this to WordPress, but we're not going to license stuff in a way that permits having value ripped off the top. Especially when it's not given back.
The database startups have gotten the memo. Nobody's licensing without intense restrictions on this kind of behavior.
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.)
