Had CXMT hit a normal functioning market, they would be a much harder sell-- existing vendors could spread FUD about performance and quality to hold them back for a few years. But now you have an audience that is desperate to the verge of soldering up banks of 74LS74 flip-flops to make their own RAM.
It's not even like they're offering a reasonable "there's a domestic product but it's marginally more expensive" alternative. And it's all their fault. I sort of wonder if someone was actually saying "we'd better keep some supply around just to avoid burning our bridges with Dell/HP/Apple/etc." when the deals went down.
The US might try to go protectionist/China-baiting to keep CXMT products off their market, but I expect they'll sell just fine everywhere else.
