To state that Phil has said nothing negative about the state of consumer VR in this interview is an outright lie. I don't think he's being too negative - maybe a little dismissive of a handful of VR games that are certainly more than just demos or experiments - but one way or another he makes several negative statements:
1) I dont think the creators in the game space have yet found well, they havent obviously perfected the craft of building VR games"
A kind way of saying that developers haven't worked out how to make good VR games yet
2) "I think VR will find its spot in gaming; I would make that bet"
VR hasn't found its spot in gaming
3) "Most of these things Im playing now feel like demos and experiments"
Most VR games aren't really games
Together they paint a picture that gaming VR isn't worth it yet, either from MS's point of view, or from the consumer's. It's a perfectly reasonable argument, but that doesn't change the fundamental sentiment of what he is saying - negative about the current state of VR, hopeful for the future state of it. I don't think it's coincidental that he's spreading this view shortly after the launch of PSVR, and that's fine, it's part of his job. What I find highly unlikely is that his statement is, as you say, benign, and that he's not remotely thinking of PSVR when saying this. Phil is an intelligent man, a large part of his job is PR, if you read between the lines... it's fairly obvious what he's saying.
