Then they can "replace" the docker name with something that works, earn revenues out of it and benefit from the synergy with their other products.
The issue is, Docker is not worth billions of dollars and these buyers are already en route to kill it with their own replacement.
If someone buy them will be mostly for the name.
That maybe be the only reason to keep him on the board there.
