Regarding the conflict of interest, we decided to handle it as follows: features that mainly benefit practitioners would go on the open-core, while features that mainly benefit enterprise deployments would not. Of course, there is still ambiguity there, but that will need to resolved on a feature by feature basis based on the feedback from practitioners and enterprises.
This is a learning process for us, but we understand this model is being used successfully by other IT infrastructure companies such as HashiCorp, so we opted for it.
