At roughly 35,000 words and filled with jargon and bureaucratic terms, the document is nearly impossible to read all the way through and just as hard to understand fully.
A section devoted to passwords injects a large helping of badly needed common sense practices that challenge common policies. An example: The new rules bar the requirement that end users periodically change their passwords. This requirement came into being decades ago when password security was poorly understood, and it was common for people to choose common names, dictionary words, and other secrets that were easily guessed.
Since then, most services require the use of stronger passwords made up of randomly generated characters or phrases. When passwords are chosen properly, the requirement to periodically change them, typically every one to three months, can actually diminish security because the added burden incentivizes weaker passwords that are easier for people to set and remember.
A.k.a use a password manager for most things and a couple of long complex passwords for things that a password manager wouldn't work for (the password manager's password, encrypted system partitions, etc). I'm assuming In just summed up 35,000 words.
In all reality it's fine. Snaps are annoying on occasion, and the Amazon search integration was rightly riffed on, but it'll work like anything else. Sometimes it's just funny to riff on Ubuntu, and sometimes people hate on it because Linux people are very .. er .. um .. opinionated. But if it works best for you then go for it.
