Dear Youdont,
You still didn’t post your point.
There were some rabbonim in Europe who were hesitant about all eruvin. They kept it to themselves and didn’t build or forbid eruvin. I agree that it is weird how some want to be machmir and have an eiruv. Proper construction and regular inspection is not a new concept.
I am getting the feeling that you are trying to defend a certain figure who was disgraced by the mattirim of the Boro Park Eruv.
