The more advertised one will win. Chrome is a joke privacy-wise compared to Firefox, but at the moment the winner is Chrome. Also the target audience is important: to the average Windows user, if Microsoft says Edge is best, then Edge is best, and Mozilla has no resources to fight back on equal terms since it's Microsoft deciding what runs on their operating system and what their users read or watch.
That is not true. Public polling indicates that most people do care about privacy, but are unaware of how software tracks them, or when aware, feel powerless to change anything.
I'm sure I have a biased view, but i hear people care about privacy in the same way they care about leaving facebook. They would like to, in a purely theoretical manner, but they aren't willing to change anything about their life to get that effect. It seems like many people only care enough about privacy to click a button.
Sure some people actually remove facebook, but the overwhelming majority of people are voting that they prefer the services offered, even with the tradeoffs. Unfortunate, but seems likely to me.
