You are right, but they also know most people won't switch. They have an entire generation of folks that don't even think about privacy.

There's also the subset of all of us who must use Chrome because <solution X> needed for work requires said browser. Google's dominance through Chrome extends to the whole ecosystem. Same thing with Apple inside their own (which is nowhere near a monopoly at 10-15% market share worldwide, thus totally fair game by comparison).

On the other hand, people hate ads, so going to Firefox might actually be better option for new users.

You can probably be identified on Firefox too: https://amiunique.org

They might and I used to be one of them, but now I use Google on Firefox isntead, because DuckDuckGo no longer yields useful results. The number of times I don't go "oh ffs, fine, !g" has been in steady decline over the last year, and at this point I've given up.
