You can have my ad blocker when you take it from my cold dead fingers. I will literally move to a shack in the woods rather than go back to late 90s level of bullshit advertising.
That's what gemini:// is for.
I’ve gone weeks using no other browser than Dillo. Usually also disable CSS for most sites.
Built in custom CSS for all sites is also a treat.
It's not really about advertising as much as it is about "bullshit" nowadays.
