This is an important distinction.
But it's still true, that using the Ada core GPL Ada compiler, which does not come with lgpl/run-time exception - you can only legally distribute binaries under the GPL (or commercial license).
This does not matter much if you don't distribute code to others (eg: break system of a car - gpl/commercial; build a web server to sell/stream movies - gpl/internal use).
I still think it's probably a mistake to have the fsf and Ada core version be so similar, yet differently licensed (because it is confusing - most are used to gpl compilers comming with lgpl/runtime exception, like gcc).
