May be. Solaris introduced Containers and Zones in Solaris 10 and over the life of Solaris 10 added new features. I suspect Linux Branded Zones was developed along side Solaris Branded Zones (which let you run a different version of Solaris in a Zone), but Sun was paying for the development effort. All that was over 10 years ago now and the memory is not as clear as it was then.

Joyent also pays people to develop Illumos / SmartOS.
