I believe in the conspiracy theory that the reason connecting devices directly to each other anymore without doing a bunch of backflips through third parties is more or less intentional. If you could send a file to your friend sitting right next to you with some sort of wifi-direct or bluetooth or even just via usb-C cable that is seamless and actually works, it would impact every web service from facebook to onedrive. You also have a chilling effect on what kinds of data you’re going to share as well.
That said, tailscale is the ticket for me. The client is BSD licensed, and there exists a self-hostable server which is floss (headscale). Works like airdrop but better.
That’s exactly what I’m saying. The reasons all exist on the spectrum from “we have no reason to care” to “We have every reason to make this difficult for you”
