You are assuming the site sticks a giant label on itself somewhere saying
"We comply with DNT."

If in your paper example, the store said "The following shelves have ISO A4
sheets, and these other shelves contain 8 1/2 x 11" I don't think you would
have a case to be mad if you walked over to the 8 1/2 x 11 shelf and then
said "But I wanted A4!!!"

This is the same thing. If the site says "I support DNT under the following
circumstances" and is clear about that, and you are outside of those
circumstances, I don't think you have any reason to be surprised.
