It is no different and it's the same old power law which the rewards and success diminishes as more creators and users are doing the same thing on the platform.
It's not about the one trick pony hit's that exist on a single platform which the article is focused on, it is indeed the continuation afterwards which a creator's following will still exist beyond TikTok or wherever their debut hit originated from.
Inevitably, The corporations, media and the existing larger influencers from other platforms will join in and ruin the platform, just like they did with the rest of the others. The over glorified algorithm has already been gamed by them to increase engagement, ads, etc such that smaller and late creators have depleting chances of being recognised.
Nothing has changed.
