Around 2000 Sun decided to restart the Self project with a embedded Self-in-Self called Klein and released Dave's improvements (including the PowerPC Mac port) while an outside group had done a port to x86 Linux.
I think it was 2006 when Sun cancelled the project again and Dave moved to IBM research.
So all the sources have been available since 1990, but with the delay I mentioned in the case of Self 4.1
Or maybe I'm just recalling what you're talking about with post-cancellation changes.

September 1991 — "Smalltalk/V code is portable between the Windows and the OS/2 versions. And the resulting application carries no runtime charges. All for just $499.95."

September 1991 — "Digitalk, Inc. announced new versions of Smalltalk/V DOS and Smalltalk/V Mac that include royalty-free runtime. Smalltalk/V Windows and Smalltalk/V PM are already royalty free. … Prior to this new policy, there was a per-copy charge for runtime applications."

It was the already quite established in big corporations, all IBM IDEs in the Visual Age series were written in Smalltalk, it was the language used alongside C++ on the famous GoF book.
When Java came to be, IBM dropped all their Smalltalk investment and pivoted 100% into Java, Eclipse was the rewrite of Visual Age into Java.
And the fact that companies like Cincom are still in business shows the extent Smalltalk was being used in the 1990's.
I've never done anything with Smalltalk, and what I know doesn't make me comfortable. For example, Visual Age stored all your code in an opaque "repository" (not a file-based one like cvs, svn, git). And a colleague of mine told me there are no source code files, just the running project that you share around and tinker with all the time.
Image based source control has been a solved problem for Smalltalk since the 1990's.
It is also a good example of how the "Python is too dynamic for a JIT" reasoning doesn't play that well, as it surely isn't more dynamic than Smalltalk, SELF and Lisp images and development environments.
Without the scare quotes we'd call that a database.

smalltalk sources fileRegarding Self's limited adoption, I think JavaScript showed that a Self-like system could be effective and popular if it used C-like syntax rather than Smalltalk-like syntax and shipped in every web browser.
