it doesn't have much with "being adult" so "copping with the crap". It has to do with:

- morals. I don't think unsolicited ads are moral. I'd rather pay. But I generally don't get that choice without an adblocker.

- More choice and ethics. Again. I'm the one to decide what I want to see, not adblock people using a revenue model where they're in a position to force companies to pay them to be on a whitelist. That's extorsion.

And.. I'm pretty sure you get revenue from adverts.
