is this flamebait? we really don't need this stale-ass debate revived for the millionth time. everything that had to be said has been said and no one is going to budge from their positions. there is nothing to be gained from reposting some old controversial 2021 blog post about this outside of more flaming. it's time to move on. this is a waste of everyone's time.
if you're a developer, support themes if you want to support them, don't support them if you don't. if you're a user, use the apps you want to use. if you care about theming, use the apps that support it. if you don't, good for you. there doesn't need to be anything more to it.
