I can see changing to charging for auto-backup capability. I'd pay for it, even though its free now. But the snapshot capability, I'd be mad if I had to pay for my snapshots (even though its storage cost). If I could have 1 free snapshot per month, and a total of 1 of my snapshots were free, and any *additional* snapshots cost then I could see that and would pay for that. but to have to pay for a single snapshot, that was the baseline of my current VM, not so sure I'd be happy at that!
