Imo, using this argument in this context not just strains the credibility, it makes argument itself sound like fake excuse. VISA/MC would not be associated with porn at all if they did not pressured on steam to remove the games. That is simply not true and non existent threat. It is censorship, plain and simple in its true original meaning.

I do not think VISA/MC do care about freedom of speech or anything of the sort. Nor they ever claimed to do so. But we do not have to twist ourselves into pretzels to pretend this is not censorship just because censorship is ugly word.
