I wouldn't call it throw away ticketing when we bought a more expensive replacement ticket, also from UA. We bought it with miles, but it accrues a lot more than $140 revenue on UA's books. For biz seats which were not available last August.
Furthermore, UA knows that many Basic Economy passengers decide to change return dates and buy new tickets. That has never been considered throwaway ticketing as far as I know.
