And then you drag the goalposts out of the country ...

As I said, C was not "closed source", it was distributed with source under a proprietary license. And "all the UNIX clone vendors" didn't exist for years after the UNIX tape was first released. And they weren't "clones", they were enhanced supported versions of the AT&T system. I worked for nearly a decade for the first of those commercial UNIX vendors, ISC ... the other prominent ones were SCO and Wollongong. (Sun came along later, based on BSD UNIX, developed for the VAX and of course derived from AT&T UNIX ... none of these were "clones" ... the first of those was Minix, and then GNU/Linux). We all distributed UNIX with the AT&T C compiler. Eventually ISC wrote their own C compiler for IBM's AIX project because IBM always had special requirements ... I don't know whether we distributed the source or not.

But the point is that this was nothing like the situation with Mojo, which currently has not released the compiler source ... which is nothing like what people on this page are writing, because it will be open source SOON, probably coincident with the conference later this month.

I won't respond further about this.
