The problem with locked bootloaders is that it cripples the phone's first few months (at least) by preventing devs from making anything useful. Then by the time the bootloader is worked around, you've got a whole new crop of hardware and the old stuff isn't interesting anymore. Apple's the worst, but Samsung is trying hard to supplant Apple as the anti-developer king. Now's the time for LG to steal Samsung's lunch by unlocking bootloaders and getting a broader developer base and CM support.
