I understand your frustrations, but ultimately plusnet own the Hub Two, they have a duty to keep it updated, both BT/EE Hubs have gone through a similar firmware update program.
I might suggest there should a mechanism to notify customers of planned Hub updates, but being in support for many years before retiring, sadly the majority of customers are unlikely going to read the notification.
If you prefer, you could consider using your own router. This will give you more control, with a highly configurable device to suit your needs.
Superusers are not staff, but they do have a direct line of communication into the business in order to raise issues, concerns and feedback from the community.
