That's quite an extreme whitewashed misrepresentation shifting who I pointed out to "anyone who ever gets upset about things hat happen". The
post you quoted included the
entire tyranny of fun explanation back in because the nuanced context of who specifically was marked out in bold & why is critical to avoiding this very reaction. I would clap at the excellent example of parody demonstrating how those people in oost 90's bold section often react but your barb seems serious.
There's nothing "whitewashed" about what he's saying and I'm not even clear what "misrepresentation shifting" would even mean in English, let alone in this context. Feels like you overcooked the descriptors to the point where it's a burnt mess and we can't tell what it was meant to be!
He's simply factually correct that the "tyranny of fun" post is a pretty bad, mean-spirited, and frankly rather reactionary (which it does seemingly admit to, at least) and thoughtless, however fancy the language used.
There's nothing "nuanced" about the larger post you link either. It's just sneering, contemptuous, and condescending! Worse, it's kind of a rather silly bit of writing that takes itself deadly seriously. Whoever wrote it had no idea what they were talking about (I can't work out who - the link to the original goes to a dead page). They're just veiling ignorance in terminally failed attempt at being "high falutin'".
Specifically, they're ascribing motives to Gygax that he demonstrably did not possess, and using this as a justification for their reactionary sneering. That's ridiculous as a position. Their whole "anti-balance" screed is way off and the "how dare anyone complain about things that aren't fun for them!" attitude is one that Gygax was pretty inconsistent on in his own works, both writing very much in favour of that, yet also coming out against it at other times. He was all over the road.
Further, the idea that Gygax (or Arneson or others) was anti-balance at any time he was working on D&D/AD&D is laughable, because the very concept of balance in TT RPGs didn't really exist (it didn't even really exist much in wargames of that era - simulationism ruled over balance! I can demonstrate with examples if required). He didn't balance things because no-one did! It wasn't really until points-based systems came in that balance started being discussed much, and not until the late '80s that you even saw RPGs beginning to even moderately seriously attempt it* (and AD&D 2E wasn't really one of them, initially). That's like saying Galen (the Roman doctor) was against CPR. Or that the Wright Brothers didn't approve of jet turbines. It's anachronistic to the point of being purely ridiculous and silly. That anyone took it serious is incredible.
Also, as pointed out, this applies more to 5E than it did 4E, so it's quite astonishing to use it as an argument in 2024 AD, especially if one is DMing/playing 5E.
* = HERO etc. had nods towards it but the first one I remember that obviously trying quite seriously to balance the characters was Shadowrun, all the way from first edition. The character creation approach was very balance-oriented. Maybe it wasn't good at it (okay it definitely wasn't), but it was trying pretty hard.
