R Ari Zivotofsky replied with a link to
in which R Barukh Efrati lists various respondants and their problems with
this umbrella with a Magein haShabbat.

Frankly, I was disappointed. The objections were about people erring and
using regular umbrellas. Or objection to overturning precedent (although
the umbrella is designed to be unlike precedent).

I mean these are all arguments that would equally apply to Machon
Zomet's work. Or a Shabbos elevator. We don't normally make such
pseudo-gezeiros. Why now? Feels to me like the DL stance was shaped more
by counter-reformation -- C and most Mesoratim allow it -- than by actual
halachic agument.

Also disappointed that my problem wasn't raised. Seems to me that even
if the umbrella is never closed but it isn't left with the canopy part
horizontal and sufficiently far from the floor, it's not an ohel. And
therefore picking it up for use would be boneh.

Tir'u baTov!
