I took a picture on my android phone the other day and noticed it asked me if I wanted to post it on Google Maps? Really, why would I want to do that. Why does any photo I take need to be on Google maps. If you go into Settings > Apps then pick Camera, then go to Permissions and disable Location. That seemed to disable this nasty feature and message. Of course you have to have Android 6.x to disable permissions for apps on specific things.
