OpenOffice for PowerPC is not dead. If it was, why would there be 3.1 development builds here:

OpenOffice 3.0 did not get enough feedback/UAT/sign-off to release. And 3.1 will be in the same boat if people just download it and don't actually provide feedback -- which is the entire point of releasing the beta versions in the first place; they don't release them just to give you a shiny present - you're supposed to cast a critical eye over it... then actually log bugs.

You want OOo PPC? Get the betas, feed it back -- real feedback (not just "I love your program but I have PPC Mac. I would very much like a version for my Mac.") -- tell your friends to do the same. Do something about it, instead of just complaining. I work in the software testing business, and we cannot get release authorization without appropriate/sufficient User Acceptance Testing.

However, it's probably indicative of the take-up of Intel Macs that they can't scrounge enough feedback on the PPC version. I've found the same -- of the fleet that I look after, PowerPC machines are now in the single-digits. So where am I to get people to sign off on releases for PPC users? So, although you may complain that they are abandoning PowerPC users, it is quite likely it's the users who are abandoning PowerPC, which isn't OOo's fault. They're just sitting there going "where is everybody?" If you've never logged a bug for OOo PPC, then *you* are the reason there's no 3.x for PPC (you cannot tell me you've never run into a bug in it).
