I miss the days of Quake where there were tons of custom levels, models, mods, everything custom thing you can think of. Was great... of course not all were that great because it was just some guy doing it, but there were some mighty fine stuff.
You still get that with games which support mods or Steamworks these days.
When an anti-piracy method is affecting the game for people who legitimately bought it and causing other people not to buy the game, there is obviously something wrong with it!
