F*** you for this forced obsolescence. The _only_ feature I care about is being able to control my A/C remotely. I was happy with my Nest for several years, and was actively shopping for a 2nd Nest thermostat for my 2nd zone, but found advisories stating this functionality was going to be removed. Given that you're removing this functionality for no reason other than to force upgrades, I will never purchase another Nest product.
I sincerely hope @Everyone else does the same.
