I was following this guy on instagram that makes the most amazing dumpster miniatures. Together with miniature trash that you can put in and out fo the dumpster.
Somehow I'm not even surprised. Train watching/spotting and train miniature making are both popular with overlapping communities, and apparently there is a smaller but still extant community of people who are big fans of garbage trucks in the way that others are with trains. Dumpsters seems like a natural extension of that.
Incidentally, train fandom is definitely commodified, but I think not to the consternation or detriment of those into trains. I wonder why some subcultures are at odds with commercialization of their interests while others are at peace with it.
