I'm sure you've already thought about this but bear in mind that as a buyer, I don't want to hear "unlimited" for things that have material scaling costs for my service providers, it just sounds unsustainable and likely to change later or be the cause of an issue.

On the other hand being free from arbitrary limits is great.

Unlimited usage like that means someone else has to pay for your usage - when the provider's pricing changes or their growth declines your usage may no longer be subsidized by someone else's. You risk becoming dependent on them without knowing the true cost of your usage, which also might not be sustainable for you.
