Pretty much, it’s just another form of collecting stuff, this happens to be a trendy thing. Some do with hello kitty, hot wheels, some with music bands, CDs, others with tools, among many, and I am sure who wrote it also collect stuff as well. And yeah, posting few Reddit posts is an indirect way to make fun of something, we all know Reddit is always hyped and cringy about anything, regardless you see it as bad or good, I think the article is trying to portray some picture about who buys or collect X.
