I just stumbled on this link, and apparently you can stop contributing to specific sites, and also select whether to contributor to all participating sites, or ones you specifically select.

It looks overpriced. I need to be signed into my Google account at all times when browsing the internet, pay $10-15/mo, and even then, it's only removing something like 50-75% of advertisements. It's more expensive than ad block, it removes less ads than ad block, and it leaves a big empty space that ad block can typically remove.

This sounds like a poor experience for the end user, and I can't see it catching on.
