Well I disagree with the second part of your argument. You are MUCH more likely to be abused by Facebook’s “partners”. If you are not logged on to Google they don’t construct a personally-identifying profile of you. They may have some log somewhere that says “this IP address read 15 reviews of light truck tires” but they don’t have the capability to just sell in a printed and bound format the personal data of CaptSpify. Whereas if Facebook had that data I could just phone them up and buy it, no questions or restrictions. I think that difference is large enough to note.

Yes, what’s annoying is that if you are using Gmail, you are automatically logged in on all other Google services, including Maps, YouTube etc. When I’m searching a doctor’s address or watching a stupid video on YouTube (most of the time embedded in some other webpage), I don’t always want it to be added to my history. https://myactivity.google.com

Now I’m using Firefox Multi-Account Containers to separate Gmail from the rest. And I am considering switching entirely to ProtonMail.
