Probably yes, but hey! Why do Cloudflare Worker would need SSH connection establishment? I do not asking Cloudflare to block 22/tcp entirely, but all this situation is very odd - I am seeing anomaly, reported abuse to them, but no explanation why this is happening.
About password authentication I totally agreeing with you, but this is a bit out of scope of this thread.
The only purpose of this article is to know the truth what is really happening. I have never seen such many connections to the SSH even from researchers.
