DNT is another bit of information that can be used to track you. It's ironic. If you enable it in your browser, then you stand out among the masses who by default, have it turned off.
any idea why it was badly executed ?
I'm not going to go set cookie preferences on every single site I visit, and especially not ones that I'm just randomly visiting and have no real intention of coming back to. On desktop it's not so bad and you can mostly ignore the banner across the bottom to read that one article/post/whatever, but on mobile it takes up a good 1/3 to 1/2 the screen and really I think that's by design - you HAVE to get rid of that to make sites usable, and the easiest way is to just click the "accept all" that's always a single click away and get on with life.
