It's not as potentially reactionary as the title makes it sound, its mostly about the company's rapidly changing strategy after the huawei ban. On the one hand, a third mobile ecosystem sounds cool. On the other though it's going to be largely proprietary as well. I hope it'll offer an ability to use apps without google dependency though if they are optimized for both platforms and beyond that it's going to be interesting to watch the platform grow and see how it can compete with google.
I prefer no backdoors and do my best to avoid as many as I can, but if I had to choose between one or the other I'd prefer the one that doesn't have the ability to do anything about the linux isos I download on a regular basis.
