Ska is simple, fun music that cares little for anything other than being fun, and is often gleefully immature. As such, teenage boys like it and pretentious music snobs love to look down their noses at it. Ska bands are aware of this fact and tend to lean into it, creating a self-aware and often self-parodying genre. It can be argued that it's not "good" music. But it is, without a doubt, fun and high energy music and a live ska show is a blast.

As far as cultural appropriation goes, nobody who matters cares, as all music is a collaborative effort that builds off of previous works. Music belongs to the world, and gatekeeping it as belonging to any particular culture is ridiculous. Ska in particular is a genre that loves to do covers, and often the sillier the better.
