That link was there this morning (UK time) but it looks like it's been censored.
I was active in that one too.
It has been removed. Basically, it was Joe Schorr proactively trying to put out a fire / calm a core creative community by saying that there would be an update "soon", with no date. It was his choice to do this, as he started the thread.
About 4 1/2 pages of posts then ensued ranging from disapproval of Apple's communication to the pro community (majority of posts) to the some saying "they can't wait", with upbeat candor. With the former the overwhelming sticking points were:
1. Slow update of RAW support for cameras
2. No predictable timeline, its unacceptability, and how it negatively effects a pro workflow
There was quite a bit of "Thanks, but your post is too little, too late..~we already moved to Lightroom"
Personally, I did not see any pot shots...hopefully it will be a wake up call for Apple on how much they irritated a core creative group. I don't think they were expecting the public lashing that that thread gave them.
