First rule of the public suffix list...

I think what gets me more is I don't see an easy way to add suffixes to the list. I'm sure if I dig I can figure it out but you'd think given how its used they'd have an obvious step by step guide on the website

Last link the menu header: https://publicsuffix.org/submit/

Which then links to: https://github.com/publicsuffix/list/wiki/Guidelines#submitt...

Fairly obvious and typical webpage > documentation flow I think, doesn't seem too hard to find.

Ok so we need a GitHub (Microsoft) account to avoid needing a Google account to in case some undocumented system decides to shut down a website we host. Great.

I agree, that's pretty dumb. But I wouldn't say "no easy way to add suffixes to the list" at the very least.
