no, there was a brief period of time where sun decided to try to imitate microsoft in this stupidity, but fortunately none of the other unix vendors followed suit

First of all, everyone else was doing the same outside UNIX in the 1980's.

Secondly, Solaris, Aix, HP-UX, DG/UX were the same in what concerns having to buy a UNIX developers license for the compilers.

So other UNIX vendors did follow suit, and I can't be bothered to dive into BYTE and DDJ ads from 1980 - 1990's to add others to the list.

though i never bought one myself, i never saw an aix or irix box without compilers installed, and don't have any personal experience with hp-ux and dg/ux, but it was only for solaris that the fsf decided they had to put up precompiled gcc binaries on their ftp site because the vendor wasn't shipping one
