Be careful what you wish for
While many people would like to get rid of Google (the spying-on-the-user Google, not the search-engine), the alternative (a Sino-Russian "influenced" version of it) might not really be what they have been waiting for.
I certainly haven't - but then I'm a certified Apple fanboi.
As such, I know that nothing exists without somebody paying the bill.
Huawei already have their own OS ready. They don't need Google in China (blocked anyway), they just need it for the rest of the world, where they need to convince users to switch.
And for that, they "just" need a couple of apps:
- Instragram
- Netflix
- Snapchat
And maybe a handful of others that people use. If these were there and would and work - how many people would switch?
A lot of Android and even iPhone Apps are developed in China anyway these days.
The devs there will develop for whatever OS people will have running, as long as money can be made in the process.
