But that should be up to the users to decide. I'll be much happier to use up 137 MB for a critical security update than 354 MB for the latest Facebook app update (version 132.0).
Hmm, interesting. Updates, and especially security updates, can be seen as a common good. It's the only kind of thing I can think of that exemptions from data caps might be a good idea for.
4G can certainly handle 137 MB in speed, but that doesn't mean users want to use their data plan for updates.
