didn't they moved actual hardware production elsewhere outside of US?

typical story. first move out production, loose core competency, let competitors copy it with own brands in own jurisdictions, and shut down business.

American manufacturing is a rounding error, especially when it comes to consumer electronics.

Western manufacturing can't compete with a Shenzhen. Our supply lines suck, our labour is too expensive for any kind of manual work, and we didn't bother to invest in automation as decades of outsourcing made our manufacturers focus on low-volume high-margin products.

No need to steal when our own companies willingly export core competency for a few cents of shareholder value!
