I think most of the MOSAIC-related projects have been put forth by foreign firms. They'll be isolated, to a great extent that way, and can set up their US subsidiaries to slough off if lawsuits hit.
Again, no difference because of MOSAIC. It's just the reality of the American marketplace. If companies think their MOSAIC-compatible product will be profitable, and if they're sufficiently funded to develop it, the aircraft will make it to the market.
