If I learned one thing, when talking with people about stuff like that: Most people unfortunately don't care. Many don't even have an ad blocker to begin with.
The majority of people on Chrome at this point are the same people that only ever used Internet Explorer until like 2015. They aren't even using Ublock, they don't even know what it is. The kind of people who have their nephew set their computers up for them.
Not sure they understand the flow on effects. Those of us being affected and work in the corporate IT space who have a lot of say in what browsers are used will simply replace chrome with Firefox on our thousands of machines nationwide without a second thought. They are digging their own grave.
Back before web browsers had ad-blocking extensions, we had programs like Web Washer. It was a local, ad-blocking proxy program that you ran along side your browser. To use it, you just changed your browser's network settings to point to Web Washer. And the ads would be filtered before they even reached your browser. It would be no problem to implement this again.
It won't do anything to their market share. At work my colleagues keep asking me "Why don't you use chrome?" or saying things like "Isn't Firefox slow?". They simply don't know or don't care to know. Also Firefox IS slow or just doesn't work, not because it's a bad browser but I've been seeing a trend of websites being designed to make it appear slow, like YouTube takes 5 extra secs on Firefox to load videos Clipcham and Adobe outright not supporting Firefox on their websites. The internet is a clown show.
I'm sure some people will swap, but nah no way it's a meaningful loss
Ad blockers will still exist too, they just won't be as effective. If the layman installs an ad blocker and gets one less ad, they won't question it further
I stopped using Chrome a while back, but still use Gmail because I'm lazy. Every time I crank open Gmail in another browser, Google whines at me to use Chrome. That grizzling pop-up is now the main reason I don't use Chrome, and it will eventually drive me to migrate away from Gmail. DON'T TELL ME WHAT TO DO!
It didn’t even make sense, because the point of Google was never to make money anyway. The point of Google was to make investors believe it was worth billions of dollars.
