I didn't say "popular for users", I just said "popular". And I strongly expect that "popular for users" and "popular for developers" are extremely closely correlated anyway, at least when it comes to consumer-targeted platforms (i.e. not Linux, where every user is also a developer).

There's a difference between "haha I'm not good at marketing, I'm glad people are still buying my stuff" and "haha I'm not good at marketing, therefore I'll stop developing for probably the fastest-growing gaming platform ever and say it's due to competition".
