The meaning isn't lost, it's as clear as day. It means any attempts by a company selling software to enforce the Licensing agreement they are selling for it.
No it doesn't. You can enforce licenses by suiing the people breaking them (which happens to companies that pirate business software and get caught). That fits no definition of DRM on the planet. It's also not DRM if you need an account to get in, ala World of Warcraft. DRM has a specific meaning.
The trouble is the anti DRM cult think DRM means software that is installed on their PCs that isn't the product they bought. Also the anti DRM cult don't even aknowledge that software companies have a right to try and protect the License of their product, which is a strikingly similar view point as people who support sites such as Pirate Bay.
Oh, the cult! How lovely. At this point if I were to reply on your level, I'd ask how much the copyright lobbyist industry is paying you to shill here. 
Software companies do not have the right to break computers (which Starforce did). They also don't have the right to install random crap on my computer, because I refuse to give them that right. If they could only manage to get the pirates to install their DRM they might be okay, except all the pirated versions just strip it out.
DRM like what they're doing here is a proven failure, only affecting paying customers. Any company run by people with a clue would quickly realize that pissing off your customers in exchange for no real change in piracy rates is a really poor trade.
I mean, even EA figured it out and dropped this limited authorization nonsense.
Somehow most of them don't count Steam as DRM even though it is possibly the most intrusive DRM out there. Don't get me wrong I love Steam because I don't have some 'DRM is bad' blinkers on but it is the truth when you compare it to other DRM. The only thing Steam doesn't seem to have that makes it better than other DRM is activation limits but it does check you aren't using it in more than 1 place at a time though.
Your major problem is that you see everybody who dislikes DRM as one group, which is wrong. Steam fits my father in law's critera just fine: buy the game and it works. He doesn't care about DRM. He wants the product he buys to work. DRM has caused games he bought to not work, repeatidly (but downloading a pirate version solves the problem). Steam doesn't have that problem.
Therefore, he has no problem with Steam.
Any DRM where the solution is to just go grab the pirate version and not install the retail one is beyond idiotic. At that point you're actually advocating piracy because the retail copy is defective. Which is the whole reason I have a problem with it in the first place.
