Following Steam's purge of NSFW games at the behest of payment processors (Visa and Mastercard), itch.io has also been targeted and forced to cull any and all NSFW-labeled games from its platform. Though the games targeted could be argued against on moral grounds, it is no right of payment processors to police speech and force their own “ethics.”
A few days ago, Steam was forced to pull the plug on a large number of NSFW games, primarily those containing certain darker and, arguably, immoral themes and scenes which I won't directly name (thanks Wccftech). This came after payment processors, primarily Visa and Mastercard, did not wish to participate in providing the means to purchase such titles, all supposedly because a group called Collective Shout campaigned for precisely that.
