The Meaning of Life, the Universe, and Everything.
1. We "deserve" the game we paid for. That game did not claim to allow mods. By definition, you do not "deserve" mods. That's a poor wording choice, at best.
2. Games on consoles don't allow mods. That's one of the BENEFITS of a console - you don't have to worry as much that someone is playing with a hacked game that gives them an unfair advantage. Sure, it can be a disadvantage when you don't get to run stuff that expands a game, but it's part of the ecosystem. The only "mods" you'll get are approved, licensed, likely paid mods provided by Mojang (er...Microsoft) or licensed partners - like the themes or character packs available for purchase already.
Don't waste your time asking for unlicensed third-party mod support - even if Mojang/Microsoft wanted to allow it, SONY would block it because the infrastructure is set up to explicitly block such things (and Microsoft would do the same on their platform even before they bought Mojang).
