(taking this in reverse order)
The separate symmetries that underly linear momentum and angular momentum themselves have a deep connection.
Components of spin are definitely a separate issue. I did not (mean to?) imply that it was the same thing.
The only honest position, in my opinion, is to expressly declare that the whole QM sequence is pop-science, not real science...
If by this you mean, "This is the general idea. If you don't push too hard on it, it will serve you well, but a lot has been left out, so don't go extending the arguments too far, because you could easily reach a point where yet more of your fundamental assumptions are wrong." Then yes, that would be a good thing to have put back in "Quantum Explanations", and maybe repeated at the top of each page.
If you mean, "This is basically bullshit", well, no.
... and, while an engaging read, has no meaningful connection to the rest of the sequences.
It connects directly to zombies and addresses anti-realist positions. Both of these are well within the 'solid' portions of the sequence. It also connects to the nature of probability, which is a core issue for Bayesian inference of real situations (as opposed to general theories).
I doubt that a disclaimer would dissuade an aspired non-expert reader from proudly proclaiming her deep understanding of the uncertainty principle and looking down at those who cannot see the proverbial forest for the (QM math) trees.
I'm having a hard time coming up with an objectionable statement that reading this (this article in particular) would produce in someone who read it at all carefully. This article hit the main point on the head, which is that the HUP is totally consistent with physical realism. It gave a correct account of the HUP for position and momentum, and showed exactly where it was skipping the work.
Someone who doesn't understand Fourier already isn't going to read this explicit 'here be technicals I'm not covering' and think 'Aha! I know it all!" unless they're the kind of person who's basically out to do what you're describing anyway, in which case this hasn't made matters any worse.
"This is the general idea. If you don't push too hard on it, it will serve you well, but a lot has been left out, so don't go extending the arguments too far, because you could easily reach a point where yet more of your fundamental assumptions are wrong."
Basically, yes. This is what pop-sci means to me: providing some understanding of the concepts, without the ability to calculate anything of value.

Discuss the post here (rather than in the comments to the original post).
This post is part of the Rerunning the Sequences series, where we'll be going through Eliezer Yudkowsky's old posts in order so that people who are interested can (re-)read and discuss them. The previous post was Decoherence, and you can use the sequence_reruns tag or rss feed to follow the rest of the series.
Sequence reruns are a community-driven effort. You can participate by re-reading the sequence post, discussing it here, posting the next day's sequence reruns post, or summarizing forthcoming articles on the wiki.
