Had a dark pattern thing only today. Got asked if I wanted to update my Java, and the damned updater had a pre-checked box asking if I wanted to change my preferred search engine to Yahoo. NO, I damn well don’t! Why would you even ask!?
And this is an improvement: previous iterations either hid the checkbox or didn’t have it at all, I don’t know which. Wasted hours of time trying to figure out why my search engine kept changing.
