I think your idea is a good one, and I’d like to see that happen someday.
I would point out though, that Apple was a behemoth company with large teams and massive budgets (essentially unlimited resources). Whereas Lemmy is just two guys barely scraping by a living wage from donations while slowly tackling an endless list of bug reports and feature requests.
Tossing Lemmy in the equivalent of a fish tank to motivate the devs would, most likely, just cause extreme burnout and a throwing up of hands. They are resource and time limited to a pretty extreme degree considering how popular Lemmy has become, and that should be appreciated and taken into account.
Alternatively, a single Merv-13 filter that’s 4 or 5" in depth (20x20x5) taped to the box fan works just as well in a smaller footprint, and still allows you to direct the airflow at someone.
