It isn't "because... reasons", it's because of specific reasons. Those reasons are actually right there in your comment: Blue Origin and Virgin don't strike me at all as "advancing space exploration". Like the comment you replied to said: we already knew how to do the stuff they've done, a long time ago. Spacex on the other hand is progressing the state of the art.
