I love the idea, but without mass adoption it’s likely not going to pay too well for as long as the majority of users are using chrome, safari, m$ edge (or whatever it’s currently called) and the owners of those browsers don’t adopt.
Most casual web users won’t passively install extensions (some will) but most will just carry on as is unless incentivised to do so.
Publishers who use adnetworks are often wedded to the revenue stream and the adnetwork controllers are hardly going to get behind a thing that leads to less adoption of their ad code.
If big newspapers got together and pushed for it in combo with regulatory assistance of sorts then maybe.
I hate using ads but generally, people are tight as bats and won’t pay for content. The moment you put up a paywall or add exclusivity in some way, many will simply hit the back button and go search for what they need elsewhere.
Subscription models, as I believe you pointed out in an earlier post, end up becoming a thing where upon review you realise you’ve 10’s of the buggers and they’re costing you a fortune.
