iOS application developers emulate iPhones on a computer to test compatibility with the device software before testing it on an actual iOS machine. Android can be emulated in a similar way. No difference there. Separating the devices for this reason is absurd.
Android keyboards are buggy with Graal from what I hear. Even though there are some that may work, iOS devices also have keyboards and controllers you can buy and attach, if I'm not mistaken. If they don't just yet, I'm pretty sure I heard about some new iPhone and iPad keyboards and controllers that are on the way. I don't see a difference between the two.
I still think it's crazy that we are separating our community because of minute differences in technology, but I understand the reasoning behind the keyboard/touchscreen advantages theory. If we can disprove the notion that Androids are easier to take advantage of than iPhones, I don't see why they need to be segregated in an online community.
