Why not? I've found I've been using Twitter more ever since Elon bought it. He's made some good improvements. It's popular to hate Elon but I think he's trying to make Twitter better than he found 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.
