This one isn't:
The Linux “team” of ATi is a one-man-show, and focuses only on workstations. Everything else is simply ignored.
You missed the part where AMD has devs working on the open driver as well.
As for the rest of your rant, everyone knows the fglrx driver sucks on Linux. What has changed is that ATI is now a subdivision of AMD, and the future of ATI graphics on Linux will be the open driver that is being (rapidly) developed as we speak, and in the end it'll be much better than anything NV is willing to provide.
Anyone brave enough to use that in-development version of AMD's open driver already knows what the future is going to look like. Give AMD another year or two to stabilize the open driver and bring it up to speed on chip support, performance tweaking, and handling corner-cases, and once that work makes it into the mainstream Linux releases, they will end up changing the world of Linux graphics support (as we've known it) forever.
After all, their driver will be entirely found within either the kernel (KMS) or Xorg itself (DRM/Mesa), so you'll no longer need a separate binary blob/package just to get hardware-accelerated 2D & 3D (anyone with AMD-ATI hardware will thus get all this goodness right out of the box, as soon as they install Linux). And thats just for starters...
