Roaming was never part of spectrum licensing so operators cannot really complain about losing its revenue. In fact, they've known for over 10 years that it was coming and have fought a very successful rearguard action to keep milking it as long as they have. Removing roaming was always inevitable as it is an impediment to single market as enshrined in the Treaty of Luxembourg. In this it is similar to the charges imposed by banks on customers using cash machines in other countries or making payments: SEPA payments and cash withdrawals are may not cost more than they do in customers' home countries.
