hm, maybe the crowdfunding platforms like kickstarter and indiegogo? as far as I know those haven't started down the curve yet. but I would guess it's inevitable once you take vc money and are beholden to your investors to squeeze out every drop of revenue you can :(

it would require a really strong mission statement baked into the company to say "we are here to provide value to our users and everything else has to come second to that". if nothing else you eventually get acquired, e.g. tumblr, and everything goes to hell then.
