I guess I just see it like JH decided to cut spending. I doubt he'd have decided to spend more, because DD was begging him for more money.
I'm also not sure DD would want to be part of a situation where he had to beg, but who knows. They might have lied to him, too. They might have said, hang in there: we will spend way more, soon. Then, not done it.
I have no idea what GM woulda/coulda done better or worse than Bloom did, under the exact same circumstances. Adding a variable about possible different budgets and mandates makes it too complex for me to ponder, and besides, what would be the point. It would be apples to oranges.
Maybe DD would have built better 26 man rosters, but the farm and foundation would be worse off. Maybe, he'd have spent the same AAV, but we'd have more longer term deals (good or bad.) Who knows?
I know Bloom blew his chance. He botched the big moves and the non moves were even worse. IMO, he did a good job on building up the farm and the 40 man roster depth. I think after the rule 5 players are added, this fall, the 40 man will be as strong as it has been since 2019 or before. I think that was the major task given to him. That grade is still pending, and it is total speculation on what the results will be, but I'm not sure other GMs woulda/coulda done much better, on that front. (For what it's worth.)
