Not much. Probably not. I don't know the particular instance because I don't follow US Twitter politics that closely. First time I heard about M. Y. was when he has blocked from giving speech at some college campus.
However, as a general argument, things that are cultural values include 1) trusting people to recognize the few who say stupid things by the virtue of those things being stupid and wrong things to say, and 2) in the public sphere of life the disputes are to be resolved with discussion. Words either fought with words, or ignored for their sheer stupidity, not by removing the words from the arena. (And Twitter is big enough that it counts as a "public sphere". It resembles more a public park where people can yell at each other than a newspaper.)
In general, it is about respect: that one respects their fellow humans to believe that there's enough civilization in left in humans that the civilization will prevail if one acts civilized. And these values can be furthered only be leading by example, because you can't make people into some mold, you can only make them realize who they can be.
Now, of course the line between free speech and speech that can't be allowed constantly muddy: one is not allowed to yell "fire" in a crowded theater, one is not allowed incite people to commit crimes. But the culture where people are allowed to say stupid and wrong things is necessary for a liberal democracy, and it does not hinge only on what kind of censorship government enforces. Why, history has plenty of examples where the government only quietly nods in the background when the private individuals enforce the censorship.
But this is a tangent to the main topic. From what I read, in this particular case Twitter is for once doing the right thing by fighting this order. It might look like somewhat hypocrite in the process of doing so, but that does not matter: While it's bad for the culture if Twitter shuts people down because that kind of thing slowly erodes cultural values of free speech, it's by a magnitude worse if the government does it as that could not only erode but crush those values into pieces.
