People who are aware of how pervasive tracking is wouldn't mind much indeed. The average user would be _infuriated_ of having to login every time they open a tab.
That's where LastPass, et. al. come to the rescue. Minimizes the annoyance of multiple logins, while increasing overall security if they didn't already use a password manager.
There's only so long that all those angry, multi-tabbing, somehow-simultaneously-both-ignorant-and-power users will be infuriated at every single website before they forget it ever wasn't like that.
