Following on from your links, if I understand it correctly, Pushpin: https://pushpin.org/docs/about/ is essentially an open source version of your service that you support (I presume you alluded to this in the interview as "OSS is a good driver of traffic for us").

I believe that is a great model for smaller SaaS companies to follow, as it reduces a lot of the risks ("use our service to reduce your time to market. If you don't like it later on, here's your out."). Great stuff!

"here's your out" is a good way of putting it. :)

When I'm on the buyer side, often one of my top concerns is understanding how I could potentially stop using a thing. Usually this comes down to selecting tools based on open technology.
