@Kiolk You are free to have an opinion, and I'm free to inform you that it's not based on facts.

Most of Android was already developed privately. This change makes no impact on how Huawei would approach their development processes. Android is not a loss leader business and does not need to resort to relicensing to recoup money by going closed source. Open source licenses don't dictate that development happens in public, and even GNU used to only publish release sources once upon a time.
