As a person who occasionally uses Twitter, but has no interest in having an account, he has dramatically improved the experience. Before he took over it was made impossible to view replies from a user, users were spammed with popup login dialogues that could not be closed with a single click, and more. I expect Twitter probably drove more people away from the site with all this nonsense, than they coerced into registering.

I also think many of the changes to make Twitter more open, such as now open sourcing the recommendation algorithm, publishing view counts (which indirectly makes it clear when something or somebody has been shadow banned), and more are all big steps forward in creating a much better and open service for all. Really most of every change he's pursued since taking over Twitter, from my perspective at least, seems to have been big steps forward.

What would you say has been irrational?
