I sure do agree emotionally with you about "fuck you Origin"... which is weird, because I also think that a monopoly is dangerous for gamers, so why am I emotionally so pro-Valve-monopoly? I guess it's partly because I know that EA _will_ try to screw me, whereas I trust Valve a lot more. Who else is as trustworthy as Valve (i.e. far from perfect, but you've gotta be way better than EA), and big enough to pull it off?
When I think about how Valve built their brand, at least in my eyes, it was a two-step process. First, make a few great games (and no high-profile duds). That's your foundation. Then add all the Steam stuff, and be careful to never ever screw me over. EA isn't good enough at step 1, and while they haven't screwed ME over, there are too many people crying and screaming for me to ignore it.
Who else could diversify the digital-distro ecosystem? Maybe Blizzard? Except now it's Blizzard/Activision, and Activision seems sketchy this era.
Maybe ZeniMax? (I dunno what Zenimax is like as a corporate overlord, but if you sum up the brand credibility of all their subsidiaries, that's a lot of credibility! I might not enjoy playing id games any more, but I respect the hell out of them, and open-sourcing all your engines is exactly the kind of trust-builder that an overlord needs.)
