This is substantially inaccurate statement.

Ada is very expressive language, perhaps the most expressive language overall
among programming languages for which more than one commercially supported
compiler exists.

But there is indeed big issue with expressiveness in Ada, which hampers it
popularity: that big part of Ada expressiveness, which is really outstanding,
pertains to concrete information (both for data and for program structure),
which is likely to be proprietary in too many cases and thus not sharable. 

At the same time Ada has poor expressiveness for incomplete (in one sense
or another) programs and components - thus making random collective 
development almost impossible.
