I don't think that's true anymore. They added message history syncing

They do. They also offer to do it when you link your desktop client, and like I said, it works on Linux but gives an error message on Windows.

Also, considering that linking requires access to your existing device I don't see an issue with that. Moxie himself considered usability to be more important than tinfoil hat-level crypto because large-scale adoption is what enables security.

The limitation is that only message history from the past 45 days would be synced. If this has changed recently to allow syncing all message history, I’d be thrilled!
