It absolutely makes sense from Vince's point of view. Strowman used AEW to negotiate himself a 1.2 million annual contract and then in the year and a half since then has stated publically and repeatedly that he would never work for another promotion. On top of that he spent that time shitting on the indie wrestling scene by calling them pathetic when they were asking for help when corona hit and they couldn't pay their bills. He has personal heat with basically everyone in AEW after the shit he got into with Brodie back when he was Luke Harper. When Brodie got released there was a lot of rumors going around that Strowman had been politicing to have Brodie fired for years because Brodie lost his shit on Strowman over that fucked up Mania Battle Royale spot that almost killed Ali. Strowman is a little bitch that won't deal with shit man to man and held a bitch tier grudge over shit he was responsible for. He has basically no friends in the industry since he is a performance center baby and doesn't hang out with the Boys, just a couple of of the Divas. Vince needs to cut some costs and the easiest way is to ditch this shitter who has gone out of his way to ensure he will never get work with any promotion. Now he can hire Strowman back at any time for a fraction of his old contract. He just needs to wait for the big fat baby to become desperate, something that shouldn't take to long because he is stupid and emotional.
Of course that is if he doesn't kill himself before then.
