Huawei's going on
It should be pointed out that the first IP theft case that led to the Huawei ban was for their attempt to steal T-Mobile's Tappy (you can't make this up) robot arm which (wait for it) tapped the screen to test its durability.
Obviously UMC's theft of Micron's technology was much less important or they would have been banned as well.
No politics to see here. Move along.
