It's more than $0. That means that when ubi goes belly up, nobody will be able to pay the bill to keep the lights on, no matter how cheap it is to do so
Not that a large corporation would ever do this, but you could imagine an indie company that cared setting up a trust with a few thousand dollars of the initial revenue, and that could pay the bills indefinitely using the interest.
For a large company, that money could've been a few micropennies back to the investors, so obviously it's silly to imagine. Also, if they really cared, they'd release the server code so others could run it.
