You are making a valid point and there might be nothing to gain remaining closed. We are not against open sourcing the code either, the main reason is that it is not on our radar, simply because we focus on building the platform and open sourcing it would be a distraction just now. There is no reason this might not happen in the future, but it will require a larger effort to focus on putting processes and tooling for the community in place, to really take advantage of open sourcing it.
