I believe that most users want 2MB+ too.
Until there is sound proof that the majority wants this, this is a false statement. I have not seen any kind of proof yet, have you?
Thank you for your concern one pool with 26% can veto othervise majority consensus for change though.
There is no consensus in this case. That would cause a network split 3/4 and 1/4. If there is really consensus then 90% seems feasible.
