Problem is data and engine just being available does not take care of everything.
First, someone has to decide to offer this as a service to other people. Nothing assures that.
He then would have to upload the data on his servers and have S.O. grade server setup, that costs a fortune, to serve all the traffic.
Then there would be the problem of transferring the actual user accounts and their credit and status.
So, this line of argument (you can always get the data out and serve them) is more like the classic "it's open source, you can fork it if they choose do something you don't like". Sorry, but this is only realistic if you have the knowledge AND the resources to do so.
