Would you prefer if someone did the same thing and kept it to themselves (or sold it to the highest bidder)? I think knowing it exists is better than not knowing it exists.
It’s kind like if I took a picture off of your facebook with your keychain, and used it to make a copy of your house key. You’d probably prefer I reached out and told you to take down the picture instead of creating a template of the key for anyone to download and make a copy along with your home address.
