I use duck duck go browser as my main and default browser, and I press the burn it all button regularly. It offers to exclude sites from the data purge if you log in, but for the three or so websites that I want to stay logged in to fill time, I just use Opera for them.
Google never had any intention whatsoever of prioritising your privacy over their advertising revenue. This technology was 100% designed to shut other operators out of the tracking and advertising market and 0% to reduce their ability to track you and advertise to you. Never in a million years were they going to spend a lot of time, effort and money destroying the source of their money. Hobble competitors, yes. Hobble themselves? Never. Not even a little bit.
