Even as a PC gamer to the bone, I really don't get the argument of "a pirated game isn't a lost sale." It's someone who *could* have bought the game and given the developer and publisher some well deserved money and it's someone who is *consuming* the product the publishers are selling.
I also don't get why some people don't like the 5 install limits; I don't know about them, but at the absolute most I'll install them on three (on my desktop, my laptop, and maybe my friend's or cousin's computer to show them what the game's like). What the hell are those people doing that they're complaining about the limit? Do they have a compulsive urge to go house to house installing it on everyone else's computers? ("Hello sir/madame. Do not be alarmed, I'm not here to rob you, I just have an overwhelming desire to install The Witcher 2 on your computer")
But by and large I actually kind of agree with this guy. Some DRM is okay (Steam, generous install limits, activation before installation), but there is a limit (Ubi's always on). Also provide paying customers a better service can help curb it; Starcraft, Company of Heroes, and Battlefield might have been pirated like it was going out of style, but the pirates got a massively gimped product (the first Starcraft I admittedly pirated like 11 years ago, but I wanted to try out the multiplayer, so I eventually bought the Battle Chest).
Also establish good relations with customers and reach out to them. For example, people like Hideo Kojima and companies like Relic can put it out to the community just how much their heart and souls went into making their games. By no stretch of the imagination will it erase piracy, but at the very least it could go a long way to stigmatize it.
At the same time, developers and publishers have to realize that factors like the world market (where piracy is the only way people can play a certain game), the proliferation of file-sharing, and the ingenuity of razor1911 or something or other will ensure that piracy will survive even the most absolute of reversals. But like how retailers and grocery stores cannot completely stop shoplifting, the games industry has to learn to accept some piracy and figure out better ways of mitigating it without pissing in the eyes of legitimate customers.
