I think it is fair to say that switching to Harmony OS (as an American) is a distinctly bad idea.
People should switch off of Windows now that Windows itself has become spyware, but exchanging one spyware for another spyware is just re-arranging the deck chairs on the titanic before it sinks.
I would recommend an easy to use Linux like Mint or I hear GhostBSD is really easy to use as well.
The OS that shows the most promise for the future is SteamOS. It doesn’t contain spyware like Windows(or Harmony) and it isn’t a walled garden like Apple.

I would never use it. But CCP has goals of getting zillions of people worldwide into the Huawei-Harmony OS - ecosystem. A great way to rule the world. Many nations already have their 5G setup by Huawei, which occupies huge business park outside Shenzhen
