I agree with you. Dortmund's main goal is to do business. They scout young talented players. And they develop players with experience. And sells players for a lot of money. And this is their main goal. The team is not aiming to win the Champions League or Bundesliga title. The club made a lot of money selling Haaland last season. They will likely trade Haller next season. This season Dortmund will probably add more talented young players to their squad.
Over the years that's what Dortmund always do and are excellent on it. So many players improved in Dortmund then moved to other top clubs for millions, making Dortmund richer and giving them funds to search for other players to start again.
Selling Haaland was quite interesting last year and people thought that Dortmund was doomed but they played very well and were able to almost get the first rank but they failed at the end.
They will never probably find Bayern this weak again. This season's championship loss clearly is fault of Terzic. If you don't go out with Marco Reus, the most experienced player of the last spade team and knows best what to do, you will be like this. Realizing his mistake, he took Reus into the game before the end of the first half, but the match was already 2-0. The team gave 11500 minutes to 6 players in the U23 status, which was in the squad and gave the chance to play regularly. I guess they will reap the fruits of this by selling Bellingham to Madrid for around 150m euros.
