That is why I pointed out the non-level playing field, this has to do with defaults and what information is given to people.

If you are e.g. a small browser manufacturer and microsoft pushes Edge, google pushes Chrome and both try theie best to actively prevent/scare people from installing everything else, that playing field is effectively not level for you. There is no market if your competitor is preinstalled on nearly all phones.

Sure you can now try to grab tech conscious people, but because they are few you will have to follow changes tour bigger competitors are making etc.
