It was always possible to modify images to produce inappropriate or insensitive content, but plugging a turbocharged state of the art image generator with virtually no guardrails into every Twitter reply and then failing to address the issue long after it was obviously being used for CSAM or deepfakes of real people against their will.. well that's worse
Notice the Wikipedia link says the problem was "put her in a bikini." The claims about "Grok just lets you undress people" were massively exaggerated because people hate Elon (perhaps for good reason) and not worse than other models.
Having clothes removed to the point of wearing a bikini is "being undressed" and I feel you're choosing not to understand the impact of being publicly sexualised in a bikini can have.
Grok is directly tied to Twitter in a way that other models don't have, so the use of Grok to do this stuff is inherently more public and traumatising for the targets.
You're right that people hate Elon and that they have good reason to do so, but you might be falling for the trap of underestimating the legitimate and unique concerns about Grok because it's easy to assign them just to "Elon hate."
