Oh, no I wasn't implying they were going to launch a campaign of evil and despair against their users :)
Regardless, for an online backup/sync service, I think a very compassionate ramp-down plan is on the order of 6 months with a few secret months of emergency recovery in the cases where people "forgot their child birth pictures were on there!" and the like.
If it wasn't a "backup your life" service, sure, a more aggressive ramp-down is fine... but for a service that tried for a few years to convince you to stick you life in it, I think it's overly aggressive.
I can't imagine their burn rate is _so high_ that it is not something they could have funded for a few extra months.
Anyway, just my opinion... a few of you have pointed out "how long does it take to move your data?" -- sure, if you are paying attention, have a stable/non-metered connection in a 1st world country and are always ontop of things the moment they happen... you are right, a few days maybe.
I am thinking of that small 10-15% of stragglers that miss the emails, miss the announcements and legitimately have important information sitting in One and don't realize it's gone until too late.
I'm pre-emptively feeling compassion for them :)
