When ADA was new, the compatability suite for ADA was also around $20k (at least that's what I remember). Since the name was trademarked, no one could sell a compiler without passing the suite. There was no way that two guys in a garage could sell a compliant compiler without getting it certified. But making a C/C++ compiler and selling it for $25, that happened. So the only compilers in the beginning were from big companies for big money.
