AT Protocol is open source, so not proprietary. My understanding is that Bluesky as a company is building a client experience, and funding the development of the protocol, but the long term vision is for open source and federation, so no central controlling entity. In fact there are already several other open source competing clients that can be used with the private beta, and Bluesky (currently) has no issue with this.
