It's not Sony or MS's responsibility (or Nintendo's for that matter) to stop a developer or publisher releasing a buggy game. As long as it doesn't mess with others system features, all three will usually pass through any crap they're given.
I don't think it's too much of an issue though. The number of games released every year that run fine is several times more than those that are broken (and even many of those "broken" titles, like ACU, are usually still playable. They just don't meet the standards you'd expect). I'd say things are actually pretty good right now, given the complexity of many PS4/X1 titles and the lack of harsh quality control from any of the major manufacturers.
If people really want it to become an absolute non-issue, they need to stop buying titles day one. It's not hard to wait a couple of days and see if it meets your standards.
