Musk could start his own Mastodon right now and do what he wants, but if he wants to bring along his Twitter network (or make it easier for any Twitter user to switch), then perhaps hurrying up Bluesky is another way to get what he wants short of taking Twitter private.
It seems like the focus needs to be on what can fight back misinformation/spam better given the context: more speech or moderation. The need for human moderation will likely still exist, but if Musk wants to accelerate the process as you say, Bluesky seems like a good way to start.
If Twitter is making choices that increase their bottom line at the expense of community, then absolutely, more transparency and open source would help with that.
