I have the (perhaps irrational) fear that sitting too comfortably in stage 3 leads to the kind of complacency that allows things like Web Environment Integrity to escape the “shower thought” phase.
On principle I believe that people shouldn’t feel forced to restrict themselves to FOSS - I use Steam and barely ever pirate games (ignore my Lemmy instance I guess); however, I think people should put some effort in understanding the consequences of always choosing the path of least resistance, at the very least.
