Here's an interesting exercise: think about how you, personally, would properly manage a large farm product wholesaler. I am assuming that none of us here know anything about farm product wholesaling, and probably most of us only know a little bit about farming at best. Now, we're all quite smart and have enough general business sense to critique business folks and CEOs of all sorts of industries, wondering "why don't they get it!?" It seems like they are morons, right?
But, back to the farm product wholesaling. If you were put in charge of a huge company in that industry, would you know what to do? I mean, goal #1 would be to make sure that your company stays in business and is profitable. And it's good to keep the farmers and the customers as happy as possible, but if anyone is going to lose out it is going to be the farmers, and possibly then the customers, before your own company is going to lose out, right? With a large company, you can wield that kind of clout based on getting to the point of having that much bulk and power. So you'd make decisions based on whatever business training you have, and general best practices, and looking out for your own bottom line.
Then, for reasons I can't imagine, probably the customers and the farmers are going to be pissed at you. Given that you've never been a farmer or a customer of a farm product wholesaler, you probably can't imagine what their specific complaints might be any better than I can. So you or I would blunder all over the place, pissing everyone off as we did, possibly without even realizing we were blundering.
Okay, it's a strange analogy, but I think it's where this stuff comes from. Some execs don't realize this sort of thing if they are out of touch with the technology, the motivations for gaming in the first place, and what it is to be a gaming customer. Other execs know what is what, are true gamers themselves, and forgo the DRM (and often forgo the PC in the process). Does a company that puts in hugely restrictive DRM have an exec that is a PC gamer, who routinely buys and plays PC games from a variety of publishers? I have absolutely no idea, and I imagine it varies from case to case, but if I had to bet I know where my money would be.
It doesn't make the company as a whole evil, but I very much understand why it is so frustrating to customers (as it frustrates me, also). Incidentally, I've never bought a product with excessive DRM or with Starforce or whatever -- just as a personal aside, I've always skipped those products entirely or bought them on consoles. Not to make a point or anything, but because I simply don't want that crap on my PC.
