If there were regulation, this wouldn't be a problem. Unfortunately, there is no regulation against typosquatting, Google is free to trust whoever they wish for compiling their database of trusted addresses, and DENIC has no policies preventing someone from doing this with .de names. The best restaurant owners can do is file a trademark lawsuit, maybe call the cops on Lieferando for fraud, and hope for the legal system to decide in their favour. Also, nobody is saying companies are more ethical in the EU. In many cases the existing legislation forces unethical companies to comply with ethical regulations, but they don't do it because they're nicer than companies outside of the EU.
