Plenty(well, some) Catholics in Poland had an issue with him for the exact same reason - just way too progressive for them. Although I do think that American Catholics are particularly.....fervent in their beliefs.
Look up some numbers, his approval ratings outside of America were rapidly declining (at least in Latin America). [1] Interestingly the US is the one place where his approval ratings didn't decline over time, probably owing to the perfectly divided nature of contemporary politics. As he lost support from one side he gained it in equal proportions from the other. But in places like Argentina, his birth place no less, his approval rating dropped 27 points as he got increasingly involved in Progressive stuff.
One data point, but I live in a progressive country in western Europe, and I have close family members who are in the "right wing / trumpist / christians" movement (which does exist in Europe too), and obviously they really disliked this pope.
