It’s a funny comment because those formats only existed to be proprietary. Sony learnt the wrong lessons from CD, which they co developed with Phillips. They saw the success of that format and wished they were getting royalties on the underlying tech.

They then wasted billions and decades in formats other companies wouldn’t touch because they had fees attached. Minidisc being a prime example. Sounded worse than CDs, cost the same. Had a recording feature people already had with cassette.
