It looks like google didn't release it in all the stores, for example, it doesn't exist in the Lebanese App Store, where I can download it.

I still don't understand why would someone want to alienate users of certain areas or countries. Doesn't it make sense to release in all the stores to get the most exposure?

On the other hand, I don't understand why someone would alienate users of certain countries unless they had a reason to do so. I like to give companies benefit of the doubt when there's no hint of a conspiratorial political agenda.
