In case you were wondering: Why is Popa being so negative and cynical on this thread?
I don’t see this issue as a regular ??????, with validity to both positions.
I don’t think this is a “ask your rav” issue.
I really think that nobody should be using this eruv.
If this was a machlokes among equals, or even among almost equals, it would be one thing.
If Rav Moshe’s psak was unsure, and just being machmir, that would be one thing.
That is not this situation.
