Re: Precisely why can't official FSF GNAT maintainers copy bug fixes in GNAT & its GCC-contained runtime en masse from GNAT GPL Community Edition?

I see absolutely no analogue to AdaCore and its GNAT Pro Assurance or Enterprise or Developer editions in the examples that you give:  GCC C library, GCC C++ library, or GNU Bison.  Please provide a URL to a company that sells restricted access to GCC C library, GCC C++ library, or GNU Bison for which source code is unavailable at time of purchase/download to the ••general public••.  I am pretty sure that no such URL exists to such a company for such FSF products anywhere on planet Earth (other than AdaCore regarding C/C++ integration with GNAT Pro Assurance and Enterprise editions).  After the demise of Cygnus Solutions, is AdaCore the only such company on planet Earth selling restricted* access to source code whose rights to copy are assigned to FSF?

* Btw, how precisely is it restricted?  Is it in fact restricted at all?
