Well, US has a market share for macOS of around 20% and Europe of around 7-8% from what I can find.
I'd also wager the main culprit is the 20-30% price hike of Macs in Europe (in absolute numbers - it's even worse considering the lower wages in most of European countries compared to the US), rather than any particular dislike.
