Yes, on AA or B6, some of them. The ones buying BE on Delta now are the same ones buying it before, but Delta pushed some of them out when they raised the price up so much. It's only because of the price increase that I upgraded last year as much as I did.

The no-upgrade policy won't bring in more paying passengers, because paying passengers don't care about defining other people as Untermenschen and don't spend their time worrying about whether Untermenschen are in the same cabin with them. They care about the experience, and the Delta experience on transcons isn't worth the price for a lot of people that have the cash to pay for it but don't feel the value they get is worth it. Thus the empty seats.
