Their response, and it's a reasonable one, is that the software is open, but their hardware isn't. Did you see the comment left on a youtube video by one of their admins? They told people to buy other hardware if they want to hack their phone. Yes, there was backlash, but the new phones are still rolling out locked tight. Motorola can make "gestures" to the world at large, but until they actually DO something about it, their answer remains as stated. If you want to hack your phone, buy someone else's hardware.
The joy of this project is that, other than the drivers, it's totally independent of the hardware -- unless I'm totally off-base -- because it works within the Linux framework of Android. As such, and wonderfully so, it can be relatively easily expanded to all the above hardware; it just needs to be perfected here and modified for the other handsets. When this works 100% it means that Motorola can lock their hardware all they want (and they will, because they hate hackers), we'll still have a backdoor.
