This is Ben, the CEO of Docker, and Solomon's partner in crime. Being based on Apache 2.0 (and adopting an open design process, having a large number of non-Docker Inc. maintainers, having over 300 contributors) should be read as a strong signal that we will not go proprietary or even "open core." Anyone can use and modify Docker under Apache 2.0 without fear of "copyleft" or similar restrictions, which creates a strong disincentive for us to abuse our position by going proprietary. Our business plans, as stated in the blog, are around commercial support and hosted services. (In addition, being Apache vs. GPL makes it much easier for enterprises to adopt us, and much easier to get integrated into projects like OpenStack.)
