As long as it does not involve installing software other than the game itself onto my computer, it doesn't bother me since I'm always connected to the internet. IMO, in the end, everyone will benefit, inluding the "honest buyers". Piracy is a nasty rain cloud over PC gaming, one of the reasons developers are leaning more to consoles, which compared to PC piracy, has very small piracy. More anti-pirate protection, the stronger PC gaming will become.
I admit that I pirate games fairly often, but wouldn't mind to see the end of it.
