That's why the premise in the grandparent post is ridiculous.
But the license of a piece of software is not ridiculous - if you chose a very permissive license, you cannot then go and choose who should or shouldnt be profiting off your software. The license was a pre-commitment.
But lots of people make this pre-commitment, but then makes a moral/ethical judgement post-facto when someone rich seems to be able to extract more value out of the software than what "they deserve", and complain about it.
