I think you're confusing errata with the moronic move WotC made with 3.0/3.5. The reason there was a 3.5 SRD was because of the d20 OGL where someone took the book, typed it up and posted it on the internet for FREE and WotC couldn't do anything about it because of OGL.
I don't think that's what really happened... but, Ok.
