To be fair, Guido stepped down because of the way the community reacted.

"The straw that broke the camel’s back was a very contentious Python enhancement proposal, where after I had accepted it, people went to social media like Twitter and said things that really hurt me personally. And some of the people who said hurtful things were actually core Python developers, so I felt that I didn’t quite have the trust of the Python core developer team anymore."

Note that Guido also was in support of the walrus operator, it's not like he stepped down because he disagreed with it.
