I think the US labs are going with scare marketing as a regulatory moat.
Force US into putting laws in place that block out China firstly.
But secondly create regulations that have some cost to comply with such that the big 2-3 labs are grandfathered in by their scale.
Yeah, seems to be the direction the US is heading in. I'm interested to see what the response to that will be from the rest of the governments in the world.
No need for everyone else to cut their noses of to spite their faces.
