So, now, the ad industry trying to talk to the rest of the world about the ethics of blocking ads is like the drunk uncle who puked on last year's Thanksgiving Turkey talking to the family about the "ethics" of not inviting him this year. Sure, it's a sad situation, but you probably should've thought about that before you puked on the turkey.
If the ad guys spend a few years ensuring that advertisting is safe, lightweight, unobtrusive, non-creepy, and fast, maybe we'll invite you back to the party someday, and start to consider web advertising less of a threat-to-be-blocked.
But for now, we're not taking that risk. Sorry guys, but you've earned it.
