Are you saying that you can search for those and that was a typo ("can't" instead of "can")?
I just opened up Google Maps on my Android 10 device with activity tracking off. They've changed the UI, now it's sneakier. I can set them and there's a faint gray text underneath that says, and I quote:
"Personal places will be used across Google products, for personalized recommendations, and for more useful ads."
Dark Pattern to the ten thousandth power.
They're literally turning my input of my home and work address as an implicit consent to enable activity tracking (!!!)
Again, there are absolutely 0 technical reasons why the two have to be related. Software of all kinds from the beginning of time has had "saved"/"favorite"/"starred" functionality, without ad tracking related to it.
