The title is a personal question. You could ask the same thing about collecting stamps, writing fanfiction, staying together with a so-so romantic partner, being an active member of a local church, etc. Maybe all those things felt great to do, back in the day. But now...

Most of the dark patterns he mentions are more (cough) features (cough) of monomania-type capitalism than of FOSS. Or just human nature. Sitting on your fat ass and blaming the poor guy who did all the work was really old before the pyramids were built. Same for the tragedy of the commons.
