All of those regulations are why my product won't be sold to EU residents. They can lease them, but if they choose to get rid of them they must be returned. Of course, my products are well worth repairing and being re-sold here, or leased to some other EU party. Now I am waiting for the leasing to become ilegal as well. Then they will need to purchase the much more expensive products from others.
