You could get a €2000 euro phone for €500, pay that up front, and walk to the local guy with a serial cable who unlocked your phone for €20.
A world in which telecoms can’t use SIM locking to offer financing on ultra-expensive phones to people who would otherwise be bad credit risks sounds like an improvement to me. Most people who can’t pay cash for a 2000€ phone are better off not buying one at all.

As I understand it, the practice remains common in the USA. Verizon, the carrier in the article agreed to limitations, but other carriers routinely finance phones and lock them until they’re paid off.
