I disagree. I can see them freezing the account - i.e. rejecting further mail to it. But if I come back after a year, I fully expect to be able to say "hey guys, I'm back, can I have my emails now?" and get at it.

Data storage is ludicrously cheap that I don't understand why there's a need at all.

Data storage is ludicrously cheap unless you cater to more people than most countries have. Years of email times 10s or 100s of millions of people probably isn't that cheap.

Drop Box reserves the right to delete free accounts after just 90 days. Is that unreasonable? Hell no. I bet they don't hold your stuff forever in case you do pay that overdue bill one day too.
