Ask HN: Why did Facebook not choose Apache 2.0 License for React?

We recently discussed how Facebook chose the MOST license for React? There were some concerns that the MIT license offers less patent protection to the users than BSD + Patent grant. But it was explained away as trying to appease the community. I believe the Apache 2.0 License that comes with an explicit patent grant would have been a better way to appease the community because Apache 2.0 License is also a very trusted license and it offers patent protection to the users. Why then did Facebook not choose the Apache 2.0 License?
