The issue here is what the default assumption Alex works from has changed. Previously, when something happened, it was an attack on all the patriots until someone could prove that it wasn't. Jack banning people who post racist spam? That was about creating the standard that censoring some people was okay, so later it could be used to censor people like Alex. Now, Alex's assumption is that there's an explanation for what Musk is doing that isn't a grand attack on the Patriots until someone proves to him that it is.
