I may have missed this answer but how to they actually plan to survive as a company since they are giving the product away? Will you pay them for support or will they start charging for the solutions to the "longer term" problems they describe which salesforce solves today? I could be stupid or naive but why have otherwise smart people invested $9M into this?
