Just because you are able to make informed choices doesn't mean everyone can. Nor should everyone be expected to.
If you think my mother or sister have the faintest idea what a web browser is, or how one might be better than another, then you haven't met my mother or sister. To suggest that they made any kind of informed choice is absurd. They were influenced by marketing, plain and simple.
Personally, I'd be fascinated to see an in-depth study showing what percentage of web users chose their browser based on true/objective criteria, as opposed to marketing, brand preference, herd mentality, or wrong assumptions. Is exposing someone to marketing really what we mean by choice?
It's worth remembering that choice isn't necessarily the pure good we intuitively believe it to be. Western consumers have an extraordinary choice of food, yet that hasn't necessarily translated into healthier diets. This is especially problematic when the choices themselves are shaped by corporations whose interests aren't well aligned with the consumer's.
99% of Mac users are installing Chrome or Firefox using Safari. They are objectively assessing it in a real-world test, and deciding that Safari lost. You're lucky there's no convenient way to uninstall Safari from the OS, the user telemetry would be a bloodbath.
Apple is a corporation too, and they have their own (quite sizable) financial interest in gimping the web as an alternative to native app distribution. Apple used to recognize this, and prioritized interoperability with OpenGL and OpenCL as a hedge against the web becoming the only cross-platform API that the Mac supported. The Apple of today has abandoned those interests and lost all pretenses of humility. They are equally as mask-off as Google or Microsoft is, pushing Metal and WebKit just as shamelessly as Microsoft crams the corpse of DirectX into things. This isn't a charity project, it is another way for Apple to control iOS software distribution, their primary service cash cow, Tim Cook's pride and joy. Apple is happy to give Google money for their Apple Intelligence integration, this isn't a grudge that they take seriously.
Apple could have supported KHTML upstream, and killed Blink in the cradle. They could have made Safari a billion-dollar cross-platform product, and won. They made this horrible bed, and now they want to users to moralize Google's victory. Why would anyone, knowledgeable or naive, insult themselves by standing with Apple here?
