How exactly does changing a logo (in one, messy looking place not to mention - not anywhere else yet) lead even in the slightest to "making twitter better than he found it"?
This is a straw man. I was not equating changing the logo to Elon making things better at Twitter. My argument for changing the logo is "why not" with my observation that Elon has made Twitter better since he bought it - therefore the hypothesis is that this could make Twitter better.
I don't think a brand change can make anything better or worse. It's just a lick of paint. Sure, the changes that come along with a brand change may change things for the better - but I'm sure we can all agree with that involving actualy changes to the product, aside from literal branding-only (and not even all of it).
Why not? Maybe, just maybe, if you're re-launching a brand it's best to do so when there's actually something to change aside from (one of the) logos and (one of the) copyright marks. It's like if Reddit bought HN, said "We're going to change this into a platform similar to Reddit", and simply changed the logo from Y -> Snoo without any of the other changes or promised features ready to go.
While the change isn't set-in-stone BAD for users, I don't see how it's good or useful at all conversely.
