Maybe, maybe not. There are other ways to support sites and site monetization is complicated. If you value what they do and you use the site, you should find some means to support it, if possible. But it isn't all on your shoulders either.

You should strive to support the things you benefit from and not just be a leech. But it also isn't an offense that merits committing hara kiri either.

I say this as someone who runs a number of sites that don't really make money. I do have a notice that says "Thank you for white listing," but the general lack of financial success of my work is far more complicated than "You evil ad block users killed my monetization!"

If it bothers you enough to ask, consider coming up with some thoughtful personal policy that makes you more comfortable than what you are doing currently.
