We're talking about an industry that has a heavy concentration of, for lack of a better word, shut-ins, who don't really like socializing and really excel at work when they are alone and not being bothered. Most of them self-taught to some degree, or entirely. Heavy technical knowledge and strong ability to deal with technical hurdle of remote work. Probably have a bad internet addiction too, and attribute most of their knowledge to it. The nature of the work also heavily lends itself to being remote, and why there were even people in the 90's(!) who were doing remote developer work.
But take another field, like say marketing, that has lots of extroverted types and lots of meetings with heavy emphasis on visual things, that no one was doing remote prior to 2020, and suddenly remote work becomes a much more grinding endeavor that can really chew up juniors. These people are not shut-in computer geeks and their work is not a fit for those types by a long shot. As much as they may hate the commute and insist that remote work is fine, the fact of the matter is that the type of work really doesn't lend itself to remote working.
TL;DR: These articles about remote work failing aren't really talking about software jobs, and your experience as someone who has worked remote dev work for 15 years isn't really relevant. You work a job that is almost tailor made for remote work.
