So maybe it should be avoided on emacs ML?

Or maybe the fact it’s no longer used, not publicly downloadable and 
usable and buyable, etc. and its advertisement wouldn’t lead to its use, 
makes it okay? at least for historical reasons/discussion?

I don’t know.  But usually it is asked not to make advertisement to 
proprietary software because it would promote its use.

It means it has no free-software implementations.  Java was a proprietary 
language once, it is not anymore:

Same for swift.  Objective-C would have been, without gcc’s strong strong 
copyleft (which, I hope, will stay, just as strong :/)
