Chrome's options for DNT are hilarious. For every other option, like spelling, they give you an order of (Yes, No) when you check the box to enable the option. For spelling correction, they encourage you to enable it with the phrasing.

For DNT, they have a lengthy explanation of how tracking is still done and totally helps your experience. Then the reverse the order of the buttons so the default is to cancel out of the operation.

Seems unlikely this was implemented as an accident.
