Earlier quoted context omitted.
Plenty of people (particularly here on HN) consider many or even all forms of advertising to be unethical. I don't think it's fair to ask someone to disable their ad blocker. For someone who never clicks on ads, the revenue generated by disabling is negligible anyway.
Even if they added a Patreon button (or whatever the "ethical" provider is this month), 99.99% of their revenue would still come from ads. Seems like some weird mental gymnastics to pretend their business model wouldn't be what it is. Like it or not, it's fantasy to pretend that donationware scales beyond individual devs. It's rarely even enough to support individual dev stuff.
E.g. I remove ads (both in their settings and with an ad blocker). However, I would love to support them. I'd probably pay them more than they'd make off of me in ads, as well.
