From companies whose main business is selling unethical software.

Naturally I am not counting those, given that they are paid in tainted money as per OP's complaint.

I don't think GPL cares where the money is coming from - we're talking about closed/open source, not ethical business models. If we did, we'd have to also go over unfettered free markets and capital flow.

FOSS and GPL aren't exactly the same thing.

We are surely talking about ethics,

> Closed-source software is unethical regardless of any of your unsubstantiated claims on its or open-source software's security.

And in that regard, there is also something to talk about regarding some prominent figures in open-source world.

Oh, DHH? Not sure how his xenophobic ramblings have anything to do with this...

If it was only one.
