Forget the technical details. I work in a corporate security department and if yours finds out what you’re doing there’s high odds they would absolutely hate it. I mean it likely isn’t an issue for org security (assuming they’re using bitlocker appropriately etc.) But not everyone over security is so rational and there are edge case attacks which may even trouble more sensible individuals. Either get permission, expect to do this in secret, or better yet just don’t.
Just to clarify: what are some of your specific complaints with bad information? I ask because I’ve been trying to fill in business hours and other info you might find on g maps for my city, and it’s definitely challenging. My new pet peeve is just how many businesses don’t bother listing their hours anywhere but proprietary services. No hours on their website and not even on their front doors.
