Musk already made it clear that he's not an absolutist, but picks and chooses what he wants to allow.
Most prominently, his public justification for keeping Alex Jones off Twitter is that it's personal for him. Which is just fine with me mind you, but doesn't constitute any kind of "free speech enthusiasm".
I'm not sure how aware people (you) are, in general, about Twitter and other big tech (fb, ggle) accommodating the government and political parties to amplify their messages and curtail the distribution of certain other messages.
I really don't know if that's something you or others might know about or consider deleterious to the operation of a free nation. You might be a proponent of those messages and opposed to the messages that previously had been systematically removed from the platform.
The problem is that allowing these things to occur will ultimately be bad for you as well..
Musk is as much free speech enthusiast as he is astronaut. He is systematically and notoriously punishing any speech he does not like. He did that pretty much anywhere he had power.
Twitter has been doing exactly what you pointed out for the last several years, shaping public discourse and directing political narratives
