Moreover, unlike us, Halo 2 players don't lose their entire game when the master servers shut down. They just have to either play the single-player campaign (which I can understand how that gets old after the umptieth time), or play on privately-hosted servers.
It's an inconvenience, but not the kind of disaster it's being made out to be. Besides, I find it kinda hard to like halo considering it popularized at least two of the things I despise about modern FPS games. Namely, regenerating health, and limited arsenals. That said, I might still sign the petition, simply out of solidarity for those losing an aspect of a multiplayer game they love.
