That was due largely to the designers of the language, Bertrand Meyer and his wife, creating the tools. The tools, the seminars, and the books were primary income streams.

Do you mean they created the tools to be unusable, so that they would get training contracts :D ?

Interesting, I wasn't aware of that, although it certainly felt like academic-grade code, which someone once described to me as "thrown together by a caffeine-crazed grad student at 3am and run on at least one test case". It's a real pity because there were some really good ideas in there, but the required tooling would have been just too much for just two people to assemble out of whole cloth.
