I am fairly glad I have stuck with stock OpenSSH that ships with Linux. This incident proves I am glad with that choice.
Over the decades, I have maintained remote access through port forwarding on my router - at one point in 2008 I put SSH on port 80 so I could access it from the restricted wifi network at the hospital my grandmother was at. I have also used openvpn. I have also used cloudflare tunnels. But in the end, I always connect to hardened openssh with key only authentication.
I'm with you- the attack surface of openssh (and my trust in damien) is a better match imo
Doing ssh through port 80 or 53 or 443 is immediately flagged.
I understand port 443 is always opened but nowadays you can’t just run ssh traffic on 443 without it being detected as not being https
