It always amazes me that companies, especially those that know their audience is tech savvy, don't test their sites/shops/systems with common things like ad blockers or privacy plugins. I often run into hidden problems on sites that go away after I allow some third party domain.

I wonder if it's just incompetence at the developer stage or a management decision to annoy users that have ad block etc. Neither really makes sense, I'm a paying customers, they shouldn't take it personally that I don't care for ads, and they are multi-million (or even multi-billion) companies, surely somebody there knows that ad blockers exist.
