Do you developers have to ruin steam alternatives - that some of us explicitly use to circumvent valve as a company - by turning them into trial/demo/steam key resell sites? Do you have to come here and advertise "Hey we're on steam" in the second sentence of your page? Really? At least give alternatives to the monopolistic monstrosity of a DRM distributor that takes a third of the global PC revenue a chance and stop spreading the steam plague everywhere you go!
I went here to look for DRM-free games and to not support the inventor and popularizer of online DRM. If you advertise steam first thing, why would I trust you to keep this version up-to-date, to not include DRM eventually, and why would I browse your game on a site other than steam, if I bought from there anyway?
