> It's an abuse of trust.

Right. Your new hairdo comes into question because we trusted you to look good, which is why we wanted to be around you, and you violated that trust. However, it is your hair to fashion as you please, no? What is the significance of us complaining about how you are now ugly? What does it mean in the grand scheme of things? What makes it more than idle gossip that will be completely forgotten next week?

No, you're not describing the problem @nyeah explained in their comment.

If you really want to torture your hairdo analogy into describing the problem, here's what it would look like:

You cut hair for people, take photographs of their hairdos, and put them up in the newspaper ads for your salon. Now your ads are suddenly showing photos of people who used to go to your salon, with Photoshopped hairdos and forged haircut dates. Your ex-customers are upset.
