I don’t know much about Spain or Italy, and I agree that Germany uses a lot of copper cables. But France and Poland? Esp. in Poland it most towns you have fiber, all new buildings have had fiber for ages. I currently pay 15–20€ / month for 1Gbps in a like 5th biggest city in Poland (not center, but not far either). In a couple of places in France I’ve stayed longer the internet was good as well (though I don’t recall the prices or exact speed details) — cities including Paris and towns. Granted this is all anecdotal and my bubble, etc.
