I think the most frustrating part of all this is the assumption that the only possible impetus for Quackity's silence is the server drama.
I'm sure that releasing a project you've been working on for months only to be undercut by a very similar project from a "friend" who has shown little care for the subject beforehand must have stung. That might have been the final straw for Quackity; who knows. But Quackity has been cagier around Dream for a long time now. Framing this as "just Minecraft drama" and "a recent change" only benefits Dream - why else do you think he would write this message on his public account, while restricting other serious situations to private tweets?
Nobody ghosts someone they used to be close with this hard unless they have a damn good reason for it. And nobody who is serious about trying to salvage the friendship would publicly all but accuse their former friend of endorsing horrible things that have happened to them.
Quackity: There's a possibility you have two fathers *laughs* and there's nothing bad with having two days, ok? One of them - one of them is a man called Luzu, and the other one is a man called Wilbur. How does that sound, son? Now we're gonna have to choose and find out which one of them is gonna be your dad.
Tilin: *puts down a sign*
Quackity: Let's see, what does it say? Move, move son I can't read it.
to me qsmp as a whole overarching thing insofar is like. Theyre not supposed to win. these challenges propose ultimatums with uncertain consequences when it comes to failure and require the success of every party involved to some degree. they say "work as a team!" and then make that near impossible with other stressors like timers and competition and divine intervention. its hypocritical and unfair and a facade. they were supposed to fail that pressure plate puzzle they were supposed to press that button and they are supposed to fail to keep all the eggs alive.
these challenges claim to be building teamwork but instead create more conflict between the characters and drive them apart with things have little to no real consequence in the end, but are devastating to the individual because with what information they have been provided, and how they interpret things, it is so very important and so very real.
to win is to have everyone work together, but with the pressure each challenge adds it only drives them further apart and then makes them feel guilty for not working well together. it makes unity feel impossible. i think it will be a story about trying to overcome that despite it all
