You are welcome to believe that. However putting words in other people's mouth doesn't lead to a productive conversation and so is against the site guidlines.
> Rochko wanted to step down, which forced Mastodon to come up with a succession plan. So I'm not sure why praise is due for this.
Because Rochko chose not to go with picking a new BDFL to replace him. Instead he setup a system where there will be no BDFL, which is what is being praised. I'm not sure why you are struggling with this concept so much...
> You ignored my question, though: "how do you know that Rails and WordPress don't already have their own succession plans?"
I ignored the question since it was clearly made in bad faith. I never made such a claim.
Edit: I'll also posit that secret succession plans don't build the same trust or provide the same benefits as a public plan.
