tail scale drop is much more complicated than literally copying and pasting on iDevice. that's literally all you do, no setup, nothing and this is just one example for one type of action.

look at all of that, lol. iDevice is literally copy and paste any file or text. the end - you don't even have to set it up.
This sounds like hyperbole. I've never used tailscale, but reading that doc:
Installation: Install the tailscale client
Sharing: Click on the share menu and select tailscale
It's a beta feature so there's also a switch you have to flip for now.
How do I copy it from my Mac to my Android?
