Got this notification when I opened Chrome when coming back to my desk after lunch.
"We changed our privacy settings to allow us to snoop on what you're looking at and shove you ads accordingly. Feel free to opt out, but we'll probably opt you back in when you aren't paying attention."
A lot. My IT company does the same. Fortunately, my team got an exception and we don't use IT's computers, but instead we manage it ourselves.
So I use macOS for work, while the rest of the company is on locked down Windows. I'd prefer Linux, but beggars can't be choosers.
