The post I originally responded to talked about the existence of a demographic that reacts with offense to open-source licenses being violated but is indifferent towards or even advocates for music piracy, and contended that their ethics is "weird". To me, weirdness implies being uncommon, but to the extent that this demographic exists, I do not think that the ethical principles they are applying are uncommon at all: as they see it, the typical GPL violation case is perceived to involve a faceless megacorp benefitting off of the work of one or multiple hobbyist programmers scraping by while making their labour available for free, while music royalties are perceived to primarily benefit very affluent label executives and industry association lawyers. Conditional on this belief, a very commonly held ethical system says it's bad to steal from the former but good to steal from the latter. If the objection is merely that the belief is wrong, though, you can't say that the problem is that some "weird" ethics is involved.
