Unfortunately “mistreat” is highly subjective. No matter what you do someone will be angry at you. I once got yelled at for taking a picture on a public beach where there was some family picnicking maybe 50 meters away. I think I was reasonable, the gentleman most emphatically did not.
Control what you can control. If you object to being a small data point in someone else’s documentation of a public experience, don’t put yourself in that situation.
Don't disagree, just saying it goes both ways. In your case you didn't care (not judging, I probably wouldn't either) about the opinions of the randos at the beach. However, in business, reputation does matter.
