It is a weird self-fulfilling thing. People talk about it like it's a thing, so it's a thing, even if there's very little actual evidence of anyone sincerely holding this belief. People repeat that there's this plague of folks requesting that projects be re-written, and while it is literally true that I have seen two or three instances of this (you link to one of them, and notably it is not anyone harassing maintainers about their choices), it's been two or three.
I actually got annoyed with this enough that I started doing a quantitative analysis; if you look at the canonical repository tracking this, it's got 44 total issues, most of which are jokes https://github.com/ansuz/RIIR/issues If you search GitHub for issues with these words in it, you get some, but many are either obvious jokes, people making issues on their own projects to think about doing this, and things like that. I never followed through on collecting it into a blog post though.
I didn't think your writing was inappropriate at all; memes are memes, and I'm convinced that this one is just never going to die, because it's taken a life of its own, regardless of the underlying truth or not. It is always worth pushing back on this sentiment, even if I don't think Rust specifically tends to actually embody that sentiment very much.

This is just my opinion and I'm sure it differs from others...
Roughgarden's class is advance and expects mathematical maturity. You may find his course quite fast and rough if you are a beginner.
Sedgwick's class is much easier. He is a bit boring and tries to use "real life" examples (in some instances) from the physical sciences to make the material relatable. This in my opinion detracts from the material. Also, he doesn't always fully explain where he got some of the big ohs here and there.
My advice? Follow MIT's OCW course (it uses CLRS). Supplement it with Algorithms Unlocked, the Khan Academy link in OP and CLRS. If you use those 4 resources and put in the work you'll understand the material.
All 4 sources have Thomas C's DNA touch to it (he is the C in CLRS). So you'll find it consistent when you read from one source to the other. After reading/hearing the same thing about 4 different times in 4 different ways it'll begin to click.
Order of easiness is probably Khan Academy > Algorithms Unlocked > MIT Algorithms Course > CLRS.
Algorithms Unlocked is like "pre-CLRS" and Khan Academy's version is the TL;DR version of Algorithms Unlocked.
