It is a "winning issue" in many, many other parts of the world, though, particularly where the Church is seeing growth.
Sure, but the Western world is central to financing the church + Europeans are massively overrepresented in church leadership - my impression is that while they want to expand in Africa/Asia there was a genuine attempt to tone down some of the most divisive social issues (though of course not abortion) in order to stop or delay the bleeding in Western countries.
I think this particular pope is not particularly likely to say things just to please donors, which is as it should be for a religious leader. (And for politicians too, but it's not quite as unexpected when they do so since in their line of work they need to appeal to the widest possible audience.) Besides, I sincerely doubt Western liberals are providing much funding for the Roman church.
