Excellent execution. I'd certainly be interested in the paid service when it comes out. The 100% opensource idea is probably a distraction you can do without at the moment. I want the paid service to be great. I won't care if it is opensource or not.
The 100% opensource is actually very motivating. We want to create new libs that everyone else can use, then the same people who use it contribute back and fix bugs for us. It's lovely.
And we can also reuse our libs later in more projects. Very awesome.
