This is just FUD, there is nothing dangerous in having an SSH server open to the internet that only allows key authentication. Sure, scanners will keep pinging it, but nobody is ever going to burn an ssh 0day on your home server.

No, it's just opsec.

I wouldn't be so sure about it, considering the things I have seen.
I'd better be safe than sorry. You can expose your SSH if you prefer to do so. Just don't connect your server to my network.
A few years ago a vulnerable compression library almost got pushed out that major Linux distros linked their OpenSSH implementations to. That was caught by blind luck. I'm confident there's a lot more shit out there that we don't know about.
