If this makes more people ignore Windows phone as a platform and just develop Android apps I'm all for it.
Anything that hurts MS and their platforms gets a plus in my book. This looks like a nice step in the right (non-ms) direction.
As GNU lover I cannot understand this much of hate toward Microsoft , Why ? Microsoft is the only not spying on you , Google and NSA and every other big name does too.So if you want blame someone there is more name's applicable to blame ( like NSA , Government , Google and etc ) to blame than Microsoft.
Assuming you don't use Play Services you can run an Android application under any fork of the AOSP, or anything with a compatibility layer for it (like Jolla or now Win10). You can run Windows applications under, uhh, Windows.
