This has become a key thing that I look for when buying new products. If the product relies on the cloud for a feature that I think should be entirely offline, the product will be immediately returned and a negative review will be left on the resellers site.
A perfect example was the early version of the Lockitron device. It required cloud access but had a one time payment. Based on that information alone I could not justify the purchase to myself even just to play with because it's a bad business model.
