My two takes from this article are:

1. The author does a good job in explaining why certain, very concrete, pieces of UI implementation make the UI "dark"

2. The content doesn't match the title at all, there is no analysis or discussion about why dark UX would have some kind of problem "in the long run", which ... kind of makes the title (to me) a bit click-baity, which I guess is also a dark UX pattern? These are confusing times.

Edit: blank line for better numbering UX.
