Aren't you pointing out the exact problem with Google? If Chrome wasn't a viable business without Google's ads subsidizing it, isn't its existence in its current form exactly the kind of anti-competitive outcome we would be better off without?

What possible browser competition can exist? The market price for a browser from a consumer perspective is $0. I will never pay for a browser. All that will happen is new ad placements from smaller companies, directly in the browser.

Since an ad browser is such an important piece of software, I imagine it will receive many donations. The reason Chrome doesn't is because it doesn't need them. I think that will change.
Also, I think it's possible you will pay for a browser at some point. Ultimately software costs money to make and we've become desensitized to that because we've exchanged that cost for advertising. But advertising sucks. For example, I pay double for HBO Max just so I don't see ads, and I'm not alone in that.
