You say that like it’s a problem. ;)
In my opinion, I completely understand games like candy crush and birds on a mobile device to pass the time, but how can you thoroughly enjoy something as intense as a flight simulator on mobile as oppose to a PC?
As popular as IF is becoming, I would assume the extra development would only enhance the experience for ALL platforms and devices. My idea being, more development is more development. win = win for both camps and a huge bonus for IF as it gets on the desktops of more and more people.
