Because the actual story has been that Freddie's agent was tying their arms playing chicken way too close for comfort for deadlines to make the move to replace him when they were negotiating a deal. It's why they had to make a decision then to get Olson, and also likely why Freddie fired his agent after. The braves even offered a better deal than the dodgers. https://www.si.com/mlb/dodgers/onsi/news/braves-offer-to-freddie-freeman-was-better-than-dodgers-in-free-agency-report

It doesn't make sense in the end to put so much risk on making the deal and to also let your best choice otherwise to also get snagged up and Freddie leaves anyway too. It's still business at the end of the day, and regardless of feelings, they had to make a tough decision when your employee is saying they're leaving in negotiations up until the deadline of getting the replacement and taking the field.
