> but the "ecosystem" just wasn't there

I don't think it ever will be, either. Ada's "ecosystem" is really the tooling. I've seen plenty of Ada, but there's always been zero (or very nearly zero) exchange of code into or out of the company. There's not much opportunity to grow a natural ecosystem like that. The tooling for C and C++ is catching up, facilitating model-based design code generation, which is the direction Ada's niche is heading. Ada didn't entrench itself as a target language early on, missing another chance to surge in popularity.
