I wasn't aware of the relationship between Shipyard and Protocol Labs but it looks like Protocol Labs spun out maintenance and development of a lot of core IPFS technology to a new company called Shipyard, with the idea of cordoning off what was a cost center to Protocol Labs, and the hope was that Shipyard would be able to find other sources of revenue beyond the services funding they got from Protocol Labs.

I'm personally quite disappointed because I just built an IPFS based system built on top of Kubo that I was hoping would take off. Now this throws future maintenance of Kubo into question.
