MS didn't blocked used games, they left it up to the publisher. There was also a system in place for lending games which isn't as ideal as today, but it was still there. Just seems like MS have tried to do something different with the console market and evolve it but it has been immediately dismissed because people can't cope with change. Nobody seems to care about DRM when Steam do it, even though it's arguably more restrictive than the xbone. We've now lost a lot of the features that distinguished the Xbone from the PS4 such as the instant game switching, and being able to play another game whilst waiting for a multiplayer game to be set up.
