Let's face it, WotC is no longer the same company that it was when it first acquired the D&D license. Gone are Monte Cook, Ryan Dancey, and all of the other people who helped make 3e a success. Also gone are the principles that they established. No supplement was supposed to require anything other than the core books. Hence, the Githiyanki were statted in both the Psionics Handbook, and the Manuel of the Planes. Now it looks like WotC has abandoned all pretense of needing only the "core books", and it won't be long before we see a repeat of the 2e days (God help us all!)
Also, WotC modified the SRD to include the controversial "decency codes". (Which Ryan Dancey was apparently against). The fact is that WotC has changed. Perhaps it changed when it was brought out by Ha$bro, or when several of their talented authors were laid off, or left the company, but somewhere along the line WotC changed for the worse. (Perhaps I'm being too cynical, but I've witnessed WotC go from being called the "savior of D&D" to being called an "evil money grubbing corporation", or worse. I'm just hoping that WotC doesn't repeat the mistakes that TSR made during the late 80's and 90's.)
