I can choose to combat the copyright claim (and during this process you check a box that says "you agree that you could have your account deleted if you don't win this claim" (something like that)), or I can give the $1/year revenue I got from that video to the scummy company that files these claims.
To me that's $1/year lost revenue (no big deal, right?) but that company now gets the revenue from this video—and millions of other videos... so they're making mint and gambling that most users won't even try to appeal.
