I guess that prior to the FSF releasing GNAT, and the DoD dropping its Ada mandate, compiler vendors had a captive audience, and could charge a serious premium for their software.
I've read that the hardware required to use an Ada compiler was far more expensive than its competitors as well. I've heard more than one person say that this was a serious barrier to its adoption in the wider industry.
