The way their letter is worded it seems that they have a rainy day fund constituted to ride out the stormy next few week and I'm fairly certain they'll come back with more details as to how they'll be acquiring funding from now on in the next few days. Maybe paid access to an API, maybe donations from large companies that use the system, maybe something else ::shrug::
Hopefully a project as important as this doesn't just dissapear completely because of government pressure.
