Although I agree with you that there's no reason to expect an equal dollar amount to produce a balanced outcome, I disagree completely with the conclusion. The paying party is a random website saying an offensive opinion, and the receiving party is a professional activist organization designed to turn dollars into utility. Why would you figure that the former is exerting more influence per dollar?
Maybe its unfair pessimism, but I definitely believe that Kiwifarms (ex) is way more efficient at turning money into targeted hate than - say - the Trevor Project is at countering it.
I guess my sense is that if you actually want to counter this kind of harm, you have to do so on a fundamentally structural level, and the host in question is the structural enabler.
