@glyph @mcc Sony distributed it to game devlopers, who were under their own contracts and NDAs with Sony and received this compiler as a binary and with no right to distribute it. The contractors didn't receive it under the GPL, but Cygnus still had their own copy that would eventually be upstreamed.
This sort of thing has always been part of the business of making and selling GPLed software.
And also the dig at Red Hat above is still just plain not what actually happened.
@glyph @mcc (incidentally I think we stopped doing this in the compiler business not long after Red Hat bought Cygnus.)
