RR44: R’ Gershon Hager & R’ YM Friedman (saigura rebbe) can hardly be called eruv-opposers. I’m not sure if they explicitly mattir it, but they have come close to doing so (not to mention others such as RZR).
I myself am not a eruv user. My rabbonim say my kehillah is to be machmir like R’ Moshe and consider it to have shishim riboi and the A1 where it meets the A406 to be very problematic, and so I follow them, and especially since R’ Roberts thinks so, but please don’t misrepresent the views of other local rabbonim.
I do agree it’s not political, and it only became political when the baalei batim decided to publish and sponsor pamphlets.
The original psak from (the present) Dayan Padwa was not make a brochoh eruv chatzeros! Even now, they are apparently “noheg” to do so but it’s a very grey area and I personally include it in my eruv tavshilin (“al miztvos eruvin”).
