I know I'm an exception. I've harboured a long (partly irrational) grudge against SI since CM4 due to the way that was handled. I've only bought 2 versions of the game since (despite swearing I wouldn't buy any ever again....).
With a game as popular as this, SI will do as they please, and people will still buy it. It's like any business or industry. Why would SI change if people are still buying in large numbers? I guess they've done the maths and worked out the number of people that will stick to their guns (like me) will be outnumbered by the increase of sales due to increased piracy protection. They might be right, they might be wrong. But it is their decision to make.
I don't have faith in SI to get it right (or is it SEGA, I'm not sure where the line is drawn these days). I lost faith in them over CM4, and I can remember the last time they tried to enforce something through Steam was a total and utter b@lls up.
