> customers experiences don't really matter
To consider it from a different perspective, perhaps customer experiences matter more in China. Technology in the US is super cool and cutting-edge but the constant shift to new technologies and the rapid deprecation of slightly old software leaves a significant body (perhaps even the majority?) of consumers in the dust.
Most state-owned banks too, popular browsers are all duel-engine. There's little to no incentive to change what's working, and customers experiences don't really matter.
