Thank - you've succinctly put into words what's been bothering me about this whole affair.
Economically, I am in the long tail (middle class 3rd worlder) and I think I've found the disconnect between me & the anti-ad folk. They are bothered by ads, and think if ad-supported sites shut down, nothing of value will be lost. Whereas I am not bothered enough by ads to feel strongly about it, and I don't want the ad-supported sites I frequent to disappear. I most likely won't afford to pay subscriptions in a post-ad world.
I don't mind individuals blocking ads, but I fear the entire ad-supported ecosystem will be destroyed if a critical mass is reached.
