There was a wreck in Co years ago, fatal, widow sued him. He was disgusted. Also there is the claim that the wreck was due to a modification made by the then-vendor of the kit, nothing to do with Mr. Columban's design. Anyway, the designer now refuses sales in N. America.
They can still be had.
What is the status of a plan, when it is not purchased from the original designer, ie a pirated plan in a place when the designer refuses to supply to that locale? I doubt he would pursue it legally, he is anti-lawsuit apparently. How about the FAA, do they care what you build?
