A competitive force in the Chinese market sure but beyond that?
It’s one thing to set up said Apps and OS in a Chinese controlled web after having been isolated but another to take it globally. China does have a large population sure but to really compete with Google even Apple they need to launch that OS across more than just the Chinese markets.
As you have pointed out already Google is walled from offering some services in the PRC but that ban ends at the boarder. It artificially stimulates a potential for said Fork and Apps store but outside of The PRC that artificial barrier ends with buying another device with a Android license. Even if a huge success I doubt that it would totally sink Android below 60% globally. They may hold # 1 maker title right now but then again it wasn’t long ago Samsung held that and before that Apple. It’s a fickle market and people change devices quite regularly.
No, I mean competitor in the international market.
This ban does not affect Huawei's Chinese market *at all*. Google does not even exist in the Chinese market, so Huawei has no need to compete with Google there.
The competition I'm referring to is only for the international market.
I see a lot of parallels between what's happening in the smartphone market with what was happening in the personal computer market 30 years ago. Apple took the lead with their walled garden because it allowed them to craft a superior user experience. However, as GUI matured, the versatility of Windows dominated the market. Just like Google, Microsoft had a suite of key proprietary software that allowed it to dominate the PC market. That's pretty much the story of iOS and Android in a nutshell.
The difference between Windows and Android is that the latter is open source. However, since Google pushes their version of Android, one could look at Android as divided into a Google Android, and the open source Android. The former would be comparable to Windows and the latter would be comparable to Unix.
Unix never took off because it never got any serious corporate backing. MS at one point was flooding the market with Windows. It was always easier to just use Windows instead of learning Unix.
A Huawei OS would be like Linux, a specialized implementation of Unix. They do have an uphill battle ahead of them, but Linux was able to establish itself in a niche market despite Windows' dominance. Would it have done better with a stronger corporate backing? That's difficult to say.
As we said before, the main issue is not with the OS, it's with the App ecosystem. App developers need to weigh the cost of developing and maintaining their apps on an additional platform versus the benefit they will receive from it. This is where Huawei can help promote its OS. If they can make it easy and inexpensive to build and maintain apps for their OS, then they can entice app developers to publish their apps in their app ecosystem.
