I agree that charging for something that does not even exist and assuming you will file for a refund is just lame. I think it is a website issue with it not being airport specific and just a general offering for ALL booked flights.

I will add that what would upset me more would be on some airlines the seemingly common changing of a non-stop flight to one with stops or changing a flight to being non-existent.

If I had to choose an airline with one of the above potentials...I would choose the bogus $10 one...more of a PIA than whole trip changing
