I must say I'm really surprised. I'm a frontend developer and probably more keen to keep an eye on this stuff but there are lots of times where I just say yes because the popup is in-my-face and I just want to scroll to the content. I guess where the article falls flat is where the author says a "proper GDPR content banner" was implemented. No online publication will do this. At least they will trick you with button…
I am exactly the same. I use UBlock Origin and Privacy Badger so pretty much nothing gets through anyway but just to get rid of the banner, I click on OK.
However, that being said, I only do it if the other choice is "Manage Preferences" or something equally vague: If I am given a clear yes-or-no choice, I always choose "No".
