"abandoning its plans to release additional webOS-based hardware."
That is the problem... there should not be any web-OS based hardware. With WebOS open sourced, devs should be able to install it on ANY hardware, thus bringing a stellar OS to any phone/tablet out there. All they need to do is write the drivers for the few manufacturer-specific hardware out there and leave the rest to the devs.
Once Google announced Android and it's plans Both RIM and webOS should have quickly went open as well. It is simply too late now and it no longer matters what either of them do. The only ones that can afford to remain closed is Apple.
This is what happens when you ignore a threat just because it is a new one, you can easily end up getting dominated. Just look at Blockbuster as a prime example of this.
