This would generally just discourage open software in general. Rebble is a non-profit and should not pretend to "own" any software or content. Eric didn't do things the polite way, but either way there's nothing to discuss here. Claiming that someone can steal something that is open source implies that they own said open source code / content. that's not how any of this works.

Reselling open source content is always going to be bad taste.
