My dislike of SecuROM is tied to two main factors:
1-Given the state of things, any arguments made that it curbs piracy are ridiculous, since just about every game using it ends up cracked in a very short period.
2-It's caused issues for me before in using things like TexMod to improve textures, because SecuROM freaks out. Honestly, it's nobody's business what tweaks I want to do to graphics and the like, as long as I'm not trying to redistribute the game.
