I still use gmail and drive for work but otherwise I'm never logged into anything google at home. Today when I tried to expand on a restaurant's hours it wouldn't let me see them without logging in, although it still worked in incognito. This restaurant screenshot is just a random other example I tried, but for the one I was actually checking google had the correct hours while the official website hasn't been updated in awhile and had the old ones (website said they're still open for dinner but they've only been doing lunch for a year or so now)
The're not a commercial service, and the database backing it is freely distributable, so it won't get cut off.
It doesn't have Google Street View, though, and attempts at reimplementing such a thing have been pretty weak, so if you need that functionality, won't help.
