White-knighting DRM and bashing DRM-Free products, is old. Goes back more than a couple of years back, at least in Steam forums. Problem is, it is not only a possible a$$pull by devs for whatever reason applicable, aforementioned etc, but even normal users have regularly expressed, strongly defended and tried to impose this particular opinion, before.
Deadlocking yourselves into an argument with them is a never ending circle and unfortunately, they can provide convincing arguments, however strongly and validly those can be debunked, countered, or even proved to be wrong by numbers (especially the one that DRM-On won't magically result into more sale numbers achieved).
Don't fall into this trap. Entering an argument with stupid people can only be lost and forfeit a case, since they will drag you down to their level and beat you with experience. They don't value themselves or their rights, they don't aspire to get a better agreement for using the product they purchase the rights to, would be normally their own problem and loss... Alas, they spread that cancer by trying to convince others, lel.
While i am not a regular at Steam (far from it, actually), i have also seen a number of people praising DRM-Free practice and pros, over DRM-ed products. Some of them, even directly mention GOG... There was even a steam moderator once participating in a discussion for/against gog's features offered VS steam's, before. Probably those people got triggered by getting steam "badmouthed" or something, lol
