Okay, let me be the one to say it:
Jim, you are a patronising, condescending arsewipe of a human being and I hope you choke on what I'm sure you regard as the beautiful, beautiful taste of your own excrement.
You've made a video here that tells us why everything else about PC gaming is awesome. Steam sales, eternal* compatability, prompt upgrades, community integration and development, vastly more content... but what you haven't done is told us why DRM is considered acceptable on PC. And then you have the cheek to turn around and say "I really shouldn't have to", when you've just told exactly why you do have to, and then failed to do so. At most you've argued that everything else that the DRM-mongers have done is great, so let's just take this little bit of dick up our holes.
You haven't told us anything about why PC gamers (like myself, I hasten to add) can go out to one of the few places on the high street that still sells PC games, buy a boxed game with a disc and everything, and then have to go back home and install Origin and sign up to their bullshit (and watch their sign-up process have a fart and lock me out for two hours) and type in a single-user product key in order to make it work. The fact that everything else about PC gaming is awesome does not make that acceptable. (Oh, and said Origin game still costs the same amount six months later as it did at the time. Blame Origin all you want, but that still doesn't make the system that has allowed it okay.)
You have outright lied about the nature of competition between online storefronts. Several of these stores are still under the control of their respective publishers and as such they're free to monopolise and gouge individual titles as they see fit. Again, this is partly the publisher's fault, but again, this doesn't make it okay. Game and Amazon and Tesco and even CeX can fight for my wallet on several titles. Steam and Origin have several where they can't.
You haven't told us why the lack of a used game market is fine. I don't trade in games myself, but there are plenty who do and I'm more than willing to tour those racks to find a couple of their bargains. GoG half-answers my side of this (although I really wish they'd post prices in pounds), but the sellers' side is still sorely lacking.
You haven't told us why it's okay that past attempts at DRM have at best installed disruptive and slowing software to people's PCs and at worst exposed those PCs to security issues and potential physical harm.
In short, you've told us precisely nothing about the actual issue and then patronised people for wondering about it. You. Piece. Of. Shit.
(The wonderful irony in all of this is that there are several answers, speaking to the long-term culture of gaming on home computers versus that of consoles, and you've chosen to ignore all of them in order to go off on an irrelevant tangent.)
