If you want to share videos I recommend !videos@lemmy.world or possibly !videos@sh.itjust.works. Both great communities to share videos, either ones uploaded to Lemmy (though probably not allowed or recommended by all servers) or on services like Peertube and YouTube.

Do you maybe mind sharing your APK with VirusTotal score so that people who want to try it can do so without giving their email away?

Sounds like you want a Distributed/Decentralized service like Nostr instead of a Federated service like Lemmy, you should join there instead, I’m sure you’d be right at home there.

Couldn’t have said it better myself. Federating with Threads would be more destructive than it would be beneficial, not to mention Meta’s horrible track record (FYI Meta was Facebook so everything Facebook did Meta also did, don’t ever forget that they’re connected).
