I just started a similar post and also considering taking legal actions. I'm sorry to discover this and see so many people affected. Me and my friends discovered the region lock after all switching to Xbox and spending our money on the new license, to discover square is blocking our access because we have a US account but are now all expats in Europe. So the devices we have are locked to the EU, as well as games purchased on it. Beyond just telling them about EU law, have you taken steps to notifying the EU customer protection?
