While the community as a whole has a collective memory, that does not mean that every participant has the sum of all that experience and knowledge, because individuals constantly join and leave the community.
This means that for some parts of the community, every new post (in this case by Wolfram) is one of "The first few times this came up" when it was "worth noting (and I confess to laughing at the same parodies that everyone else did)".
Because of the nature of Hacker News (the focus on individual stories (links)) the only way for new members of the community to be "nudged in the right direction", as it were, is to come upon one of these comment sections and either see the problem for themselves or see it called out (as here).
"[When there is a single Official Wolfram Ego Bitching subhthread in every thread discussing Wolfram], then everyone can enjoy complaining about Wolfram's ego there, without it taking over the rest of the discussion. (This would work better if HN offered a way to "collapse" subthreads.)"
And now we actually have collapsable subthreads!

dang's post attempts to do this. HN has poor tools for surfacing such actions and intentions (it has poor tools in a large number of ways, but the very tool paucity also creates, at times, some useful positive dynamics).
Sometimes you want low friction, sometimes you want high friction.
A wheel, particularly in the flanged steel-on-rail or rubber tyre-on-road varieties, is a device for offering exceptionally low friction and resistance in one dimension, and very high resistance in another. Among the results of such a dynamic is the property, literally, of keeping a vehicle on track.
I think HN's quirks of high- and low-affordance capabilties operate somewhat in this nature.
There is a way out. I believe in you!
