Except last time, you know... The whole botched upgrade to iOS10? Where you needed to CONNECT to a PC? Besides, people (some) still sync to their PCs. Plus that is not even the point. The point is why just leave a legacy version when they don't have to? When they can just update it as well... Of course it would hurt them... Again... Why would they not give Windows the latest version? I could understand prioritizing Mac users, sure, but just leave a legacy version won't cut it, specially if Apple wants PC users to keep using their store and buying stuff. Remember, that's what it is for. PC users get a little taste of Apple software, so they might want to switch, if they just leave a legacy version, that won't do Apple any favors. You are creating a problem just for the sake of it.
