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.
Congratualations on never actually bothering to block JS and find out - you know, facts. From actually doing so over many years, and so from actual experience I'd say completely non-functinal sites are about 25%.
I’d put the number quite a bit lower than that, probably comfortably under 10% of sites I interact with, though the trend is definitely upwards, drastically so among interactive things (which are probably worse than 50% broken these days).

This license model fits this product quite well.
