I completely agree with you. Either you take the cash or you don't. But if you take the cash, you shouldn't be mourning afterwards about not having enough money (while spending close to 1/2 million a year on ec2) and not being able to decide which ads you run on the site you simply don't own anymore.
Deciding to make it public how much you care about your users opinions of you advertising might convince a few people to turn off AdBlock. Reddit already has a reasonable number of free/unsold ad spaces.
