InControl 2 Subscription for Balance 710/210

I have previously been able to purchase a InControl 2 subscription for our multiple Balance 710s and 210s as we have literally hundreds of routers out in the field that connect back using Speedfusion.

We are now being told this is no longer an option. Why is this?
Purchasing the extended warranty is a very expensive cost to have to do every year.
We only need to keep the access to Incontrol 2 current for the Speedfusion settings.

We add new clients constantly using these routers, and purchase the subscriptions for all of these routers. This would be a big enough change that we would have to start looking into other options for routers as this adds an incredible burden for each router.
