There's no numbers there to show that disliking fame was bigger than compared to now. Billie Eilish has written big hits about not being happy as a result of fame or the downsides of it.
Also, look at the amount of anti-AI/anti-big-tech memes/commentary/activity today. You can draw a straight line from No Logo to that. And I don't think it's that hard to extend that line MUCH further back than Naomi Klein. Open Source itself has plenty of adherents and is inherently a don't-sell-out movement and mentality.
"Selling out" as a concept back then only came about because everything felt fake and contrived (to some people). Just like today, not everyone would agree that everything is fake and contrived - look at how many people are still listening/watching some of the "nepo babies" or suspected"industry plants"...
The pop-culture part of this article is just "I have nostalgia for this thing I remember and knew a lot about" while ignoring the pre-existing-and-continual Michael Jackson / New Kids on the Block / Vanilla Ice / N Sync / Britney Spears mega-stardom super-celebrity mainstream hype machine that was also massively successful through the whole period.
