Please consider that in developing countries, most of the phones (Android, most of them) have precious little memory, users often have to delete apps, in order, to say, take an extra photo.

Sure, but that doesn't really answer the question: Why delete this app and not another one?

Most of the really cheap androids already offer an SD card slot. Plus, the cheap androids dont have that little bit of memory; this isn't the age of flip phones and crappy java apps anymore (although I guess android is java).

Not all apps install to SD. Not all users have an SD card installed. Updates to pre installed apps (including google services), take up a lot of room.
