Besides for not being unexpected, I must say in most places most Haredim don't buy in Supersol anyway. Many of the products are not mehadrin, and people generally seem to prefer to shop in a supermarket they know they can shop in easily without triple checking each products for hechsher. Additionally, most Haredim dont want to pay the higher prices at Supersol.

so the trending "bye Supersol" is likely more talk than walk, unless they also ban Yesh and Yesh Chessed stores - the mehadrin chain under Supersol ownership.
