They make it easy to get a debit card (CC costs extra even with those banks) - but you can only use it at an ATM 5 times (usually per month or per year), you have fees if you use it for certain purposes, and you can’t get a regular GiroCard (which is free, always and for all purposes).

So sure, you can get a debit card for free, but that's got so many asterisks attached, it's not worth it.
