I would classify Wero as US-dependent in multiple areas, since they incorporate US-based trackers. Also in a way that I believe is violating the GDPR. On top of that, the Wero app incorporates a US-based bug tracking system that the user cannot reject, other than maybe blocking it it with a firewall. I also have not seen them officially supporting any of the EU-made operating systems yet. Mandatory Notarization (by OS vendor) in iOS and Android is adding another US-dependent layer.
While there is more EU in Wero than in Paypal, it would be a false claim to call it "EU independent".

Certainly a network. Ideally one that has no points of contact with any ad tech at all.
