My contention is that wouldn't matter. If they did adapt to the Chinese market and seriously started to eat market share from the likes of Alibaba I GUARANTEE you the rules would change to Amazon's disadvantage.
Apple and Microsoft both have products that don't have any Chinese equal. Competing with macOS or Windows is probably the hardest thing to do in the software world at the moment.
Other brands too. You don’t see the government changing the laws so Li-Ning can beat Nike.
