"Not motivated by money" in this context simply means not being profit focused, so breaking even and/or revenue enough to hire some more engineers is probably the monetary goal
Hey, our infrastructure is already being paid for by existing users.
Our pricing plans are designed such that you cover your own storage + bandwidth costs, and then some more. We don’t have a "forever-free" plan, and don’t intend to have one.
And the compute requirements for a product like this are low (since most of the computation happens on the client).
So currently what we need money for is employees (engineers) and not infrastructure.
"not motivated by money" sounds very much like "we'll be shutting down in 2 years"
