That's a very interesting observation. Google will thus prevent a native payment option at all costs, which leaves a huge opening for Brave or another payment provider. (Which is enhanced by content providers being threatened by AMP.)
I don't see Google in a very secure position. Their employees nowadays don't seem to care which will become a huge problem once Google has to actually react to a changing market. Amazon is getting product searches and Facebook can take over everything else whenever they want because Google's results don't come from analysing the web but from showing the pages that other people with the same queries are visiting.
Additionally, Huawei is forced to setup their own app store. If they have the better TikTok app, and online payment with wechat, the next generation of users will switch. China has so much more developers that a Chinese app store will become the more interesting place for new apps. With Zoom and TikTok, they have shown that they can create competitive apps.
