I've turned it off, but I found out that it removes a very useful feature: I can no longer set a home or work address. Why is this? You could've easily just stored those two addresses and not track everything else. They are clearly incentivizing the user to turn on activity tracking. Now instead of just typing in 'home', I have to input the entire address.
Yes, this bugs me too. They are also discouraging users like me from using maps at all, which is fine. Their app, their rules. maps.me, here we go maps and osmand all work reasonably well. Sometimes they aren't very good at finding addresses, but you can usually get the coordinates from an address using a separate tool or a web-search.
You also cant use the Google Assistant on your phone without turning on the Voice & Web Activity afaik. Its terrible. I switched to DuckDuckGo and dont care much about giving up some convenient features anymore.
