Except that they DO give you the source code to pretty much everything except the application market program, allowing anyone (not just OHA members) to do what they want with it (such as random people porting it to netbooks, someone porting the application layer to run on top of desktop linux, etc.). That's definitely more liberty than EZX was ... by a LONG shot.
The other big difference is that because the core Android team isn't a handset maker, they have no reason to be guarded about it like Moto was. And the various handset makers don't view it as giving control of their handsets to a competitor. Thus, it's spreading beyond a single handset maker, and it's gaining more mindshare than EZX ever had.
