I completely agree that parent conferences should be on zoom for now on. I loved not having to drive in. Back when the siblings were little, we had to plan for child care in order to attend. Zoom conferences would make this all so much easier.
OP- even my aged ILs who are not technically savvy figured out a zoom call. You have reason to complain!!!
