Whether these claims are real or not, they do illustrate one of the crazy things about technological progress. Capabilities that are difficult for states to develop eventually become something corporations can easily implement, and from there they become affordable for private citizens, first to buy, and then to DIY.

Two obvious and concerning corollaries are that state capabilities eventually become easy to obtain for non-state terrorist groups and, later on, unbalanced individuals. Consider what ISIS would have done with these, and then think about what the unabomber would have done.

I'd fully expect this particular company to face multiple hurdles in actually exporting any of these missiles. They might not be able to actually deliver at the quoted price-point. China might not permit it, due to the political blow-back. Israel and the U.S. obviously have an interest in making sure none of these missiles wind up in Iranian hands. The execs of this company are probably feeling a bit like a target has been painted on their heads right now.

However, controlling technology like this is ultimately a game of whack-a-mole. If this company fails, gets regulated, decapitated, sucked up by the Chinese military, etc., ten other companies will pop up all over the place that can produce the same thing or better, cheaper. There's also a supply chain of components behind this company that can now export critical parts to those building their own. We've simply reached (or are about to reach) the point where missiles of this sort can be made very cheaply.

Here's hoping missile defence gets better and cheaper fast.
