A vocal minority of e.g. GPL proponents is just like, really really mad about it.

They tend to claim they are worried about open source. Really they are worried about a smaller sub-culture of open source who doesn’t want their code used for profit without being paid.

What about the sub-culture of open source who doesn't want their code used for profit without the result also being open sourced?

To put it another way, why should we have to treat Microsoft's EULA and licenses as ironclad while Microsoft gets to ignore licensing terms of code they want to use for their own products? Seems like an imbalance that's only possible because one side is more well-funded than the other.
