From the article it sounds like they had strong market share in Digital Cameras in the early 2000’s. What really killed then was phones becoming the dominant form factor
You imply a major if not the only real factor in all of this, the self-destruction America engaged in to “fight communism” by advantaging others at its own detriment. The simple version of this matter is that in the 70-90s it was Japan, from the 80s Mexico/Latin America, from the 90s on it was China, from the 00s India, etc.
In essence, America was ruined by a kind of fast talking con artistry by people with selfish interests. America has fallen to con artists … “listen here. What you really need to do is help others in my interest, and not help your own in your own interests. That’s the smart thing to do. You see?“
It's just that the cell phones took over that job. (And a dozen other ones too.)
