> When people aren't willing to pay for 1-2 coffees for a month of unlimited music streaming are you really surprised that companies have no choice to use an advertising revenue model?
No. But I get the sense you're trying to express moral indignation at such users, and I don't see the logic behind that. "I like $site_owner therefore I whitelist $arbirary_third_parties whose behavior cannot be controlled nor even really measured by $site_owner" isn't a workable/scalable lesson to try to teach users.
To be clear, I also don't see any reasonable argument to be morally indignant about Spotify blocking the blockers. This is the web as it currently exists.
