While this highly intellectual super respectful morality debate is going on, I'd like to tell of my own adblocking experience.
I use Firefox on both PC and phone, and I use Ublock Origin with everything turned on, and I mean everything, up to and including the language/country specific filters. Let's just say, the only time I see ads are on my phone's Instagram app, the last bastion of ads shoved up my eyes. I don't even get the "you're using an adblocker turn it off nao" message.
As for YT on phone, I use Revanced, I intend to turn Sponsorblock off for certain creators with entertaining enough ad segways, like the guy with the tech tips. I keep forgetting to turn it off though...
