I feel like most software isn't designed with the most conservative policies in mind when it comes to data usage (Facebook does a great job though, I'll admit).

I feel like most software isn't designed with the most conservative policies in mind when it comes to data usage (Facebook does a great job though, I'll admit). Part of the reason might be that software engineers at companies like Microsoft and Google have unlimited data as a perk with their employees' personal cell phones (even still on Verizon today when a regular Joe cannot even get unlimited data anymore). After leaving BigCo, I never upgraded my phone again because of the perk.
