I think you're misunderstanding Motorola.Why modify the bootloader to disallow downgrades? To what purpose?
Try looking at this this way:
You're the hardware manufacturer. You release a smartphone; it has some vulnerabilities. You release patches to fix them, but there is a way for hackers to get the device back to a vulnerable version. What will be your next move?
Right. To remove the possibility of restoring the device to a vulnerable state.
Motorola isn't doing anything malicious there. The DROID2 GLOBAL was marketed as a business phone; on a rooted device they have no way to ensure that your Exchange-related data is secure.
