Can you give me a quote where they outright say this? Because my hunch is that what they actually say is something along the lines of 'because it doesn't have the security requirements that we desire' which would be true. Whatever their reasons for those choices, it also makes sense to limit scope given the extreme constraints they're working under and that scope is best limited to phones with the widest security feature support for their security-focus Android OS.

Grow up.
