I guess you can also draw similarities to the MS/IBM joint venture that was OS/2, but that actually released products - even if MS dumped it for NT.

Pity as SOM was much better alternative than COM, and OS/2 in general.
However that wasn't the only issue that nailed OS/2's destiny, higher hardware resources and lack of proper management direction from IBM side also played a big role.
