Explain to me why you are completely ignoring the EA example. EA threw out some pretty crappy DRM on top of Spore, got a lot of flack for it, and then released Sims 3, (shortly after the event), followed by DA and ME2 all with simple disc checks and the options (it's still an option) to grab an online account and get more content for additional moneey. People voted with their wallets, were not silent about their rejection of DRM and guess what, EA is not using the OA plus limited install limit on their retail products anymore. This is a real life recent example that completely contradicts that article and what you say. I've not seen any metric that suggests DA and ME on PC was a failure or a loss for them. Do you have that data?
Actually this is where you are wrong. Spore was a massive financial sucsess. It sold in droves, DRM or not. I think the expansions didn't do so well but that's because Spore was a bunch of shit and everyone who bought it realised they'd been robbed. But as for Spore, people didn't vote with their wallets, well some may have but Joe Bloggs bought 2 copies.
I suspect the reason EA went without DRM on Sims was because someone in the company had their ear to the ground and up until then EA was the Devil's own company on every forum you ever visited because of 3 letters, DRM. I suspect that was either an experiment or someone in the company made a good argument about why DRM wasn't doing their reputation any good.
Another thing that was significant with Spore was that despite the DRM and how much EA payed to have that in the game, and even despite it's huge sales figures success Spore was still one of the most pirated games ever. I think that went a long way to letting EA know what a waste of money obnoxious DRM was.
