Do you really think most buyers of SimCity are going to be informed by a suitable press prior to purchase if that press existed?
We do all the time. We've just had the EU say digital downloads need to be resellable, forcing Steam to allow a resell option, or whatever the ruling was.
Sure, but most times that has zero impact. I didn't agree with the pricing policy of CDs. I refused to buy them. The end result is I didn't have CDs when everyone else did because they were happy to pay that much. That's the way free market commerce works - largest common denominator, and if the largest common denominator won't change their buying habits, the market will continue to exploit them. That's a discussion for the RSPCA forum, of course. Suffice to say as long as companies can employ DRM to the betterment of their bank balance, they will. The chances of consumers forcing the issue with their wallets is low so there's little reason for those who'll vote with their dollars to expect most other folk to follow suit. If you want other people to change buying habits, you need to provide a direct alternative. SimCity with DRM versus SimCity without, and you'll get buyers voting with their purchase option.
But consumers do have the power to effect change.
Games are ridiculously low priced because consumers are resistant to pay more. That is entirely a consumer driven thing. Developers and publishers are going out of business because they don't want to risk alienating consumers.
Publishers also put a lot of focus on successful sequels because consumers have said, with their spending dollars, that they really want more of the things they enjoy. They then use the money from those bankable assets to fund development for new risky IP in the hopes of finding another bankable asset. There's a reason COD, Madden NFL, Battlefield, etc. only change in minor ways. Players want more of what they enjoy. You deviate from that too much and you will likely lose almost all of your paying customers.
Publishers are also realizing that just making a sequel isn't enough. If you change it enough that it no longer offers consumers more of what they want then consumers reject the game and Publishers suffer. And hence you see what used to be a bankable asset turn into a loss generator instead. Overtime, just like many other things they'll learn or they'll go out of business.
If change doesn't happen, guess what? The consumers (the majority) have voted with their spending dollars that whatever X person doesn't like isn't a view shared by the majory of paying customers.
At no point is regulation required, IMO. The market will decide what is acceptable and what isn't.
In the case of gaming, I think it's pretty obvious that always online connectivity, DRM, and other such concerns are extremely minor for the vast majority of consumers. And that what is far more important to them is the quality of the game and experience.
But DRM and always online connectivity get a lot of attention due to the vocal minority. Sales on the other hand, don't reflect that vocal minority because the vast majority of people just don't care. It's not an important or even noteworthy consideration for them when buying something.
And consumer spending shows that quite well. A well developed game that people enjoy playing doesn't sell more without DRM than it does with DRM.

Hell, Quake or was it Quake 2, had a method to automatically install .DLLs that were required by mod packages. Carmack had to remove that ability eventually due to aholes abusing it to do things like wipe people's hard drives.
