Yes, I think that's the objective for the licence. Reading slightly more into the product (Halo 2), they would benefit from more adoption by others as it could facilitate cross-chain interoperation.

The license model gives everyone equal access to the code, and equal rights to improve Halo commercially (make money?) with the promise that they subsequently open-source their improvements after 12 months.

This license model fits this product quite well.
