I think the main problem is the FSU manufacturers have an inferiority complex about the apparent fanciness of Japanese cameras. I do not find the FED2 to be more complicated to use than a Japanese SLR. If anything it is easier, since you soon learn to guess exposures and you quickly learn what works and what does not work by studying your own pictures. Actually, having a simple camera encourages you to do this.
All that has been said before, just as it is evident that quaint, clunky cameras with a pre-war style and zero brand image in the Western world have no chance in our markets, which are dominated by advertising signals, by what is trendy and neat and makes you look slick and smart. If FED produced a digital that was otherwise the same as the traditional camera, I'd look at buying it. But very few others would, I suspect. One of the main reasons I don't have a digital (apart from being a cheapskate) is that I don't like the "feature overload" of DSLRs. Why can't they keep it simple? Japanese marketing practice - drown the consumer with fancies that create the illusion of progress. Yet there has been no progress where it counts. Very few DSLRs will take a noticeably better picture than a well-adjusted FSU rangefinder with a good lense.
At the very least, FED/Kiev etc could have made an effort in the early 1990s to exploit their cheapness, brilliant lenses and old-fashioned, timeless looks. They did not because a bureaucracy can never become an enterprise. This is a matter of the people who advance in a bureaucracy, who of course are quite different from the people who advance in a competitive enterprise. I have seen this with my own eyes, having worked in both types of organisation. I have even seen a bureaucracy attempt to change itself nto an enterprise - and fail hopelessly. The British privatisations of former monopoly utilities provide ample lessons in what happens when you fiddle with big organisations that don't want to change.
It boils down to an opportunity missed - and now the window is shut. They can't catch up and get into digital now. If they want to salvage anything at all, they ought to get on the net and push the rangefinder cult, offer products, services, high quality film development and so forth. It's a niche market, but niche markets can be profitable.
