Funny how your ode to Nothing at all failed to mention the details of the workaround.

Basically you give Nothing your Apple Account ID and password and then all of your messages get sent to a bunch of racked Mac minis running instances of Messages. The mini logs in as you and then forwards messages back and forth.

So if you don't mind giving a third party your Apple ID credentials (which is also tied to Apple Pay and Apple Savings) and if you don't mind the security implications in having all of your messages forwarded through Nothing's servers...

Then yeah, it's a "great" solution.

Otherwise, stay away. Stay far, far away.
