Google was already in the middle of a class-action lawsuit regarding the incognito mode, where they were accused of tracking user activity. And, they agreed to settle the lawsuit.
To conclude that and move on, they will have to make the necessary changes to prevent another lawsuit against them.
An even better course of action is for people to switch to a browser that care about users’ privacy and block trackers by default.
Google makes billions from targeted advertising every year, don’t expect it to improve privacy unless it’s forced to by regulation or competition.
