I think they were made for governmental purpose, not for regular people.
I can imagine that quite a few companies outside the US are going to build some of their core IT around this CPU. The CPU price is quite low if you consider what the data is worth.

FTFY
Say you're in the west. NSA has backdoors into your US-designed hardware and your US-designed OS. NSA also, probably, has access to your ISP's routers and US net/web corporations like Google. As a result, NSA may hide C&C channels where KGB use of a backdoor to your hardware would still show detectable illegitimate network traffic.
Lower risk of detection translates to higher probability of use.
