As always, I would focus less on the legalese and more on the practical effect. Technically, you only own a license for any digital game, or any physical game that you buy. The enforceability of that is incredibly suspect and - to my knowledge - hasn't been tested in decades, and we live in a very different world than when those contracts first started being utilized.
But either way, what matters is what you can, in practice, do with the game. Whatever the contracts might say, if I buy a game on GOG, I can keep it and do whatever I want with it. If I buy a game that has to phone home, I can't. The EULA is the same between the two products, but one is obviously worse than the other. Xbox games don't require you to phone home as long (unless you're redownloading obviously), and this change in language doesn't affect that, so... it's really not a big deal as far as I'm concerned.
