Yeah. At best, it is clueless.

I think it’s maybe possible that they have a thriving community on Reddit, and not much interaction with people on Mastodon, and they can’t afford to invest the time to pay someone to maintain both, and so some middle-manager who’s not exactly a tech and privacy expert decided to go with the more active one.

You’re completely right though. Even in that super-charitable fantasy scenario, it would have been better to shutter the Reddit community, explain to the thriving community why they would be better served by a different platform, and keep going on Mastodon even if it’s something like 5 people.
