Same, when for TikTok specifically their innovation was quite minor- no one (besides Vine) had built a short content video feed that was designed for engagement vs. social qualities- the Instagram feed at the time still had social elements in the algorithm. This applies to every level of technical innovation (AI, cough cough)- that the super-hyperbolistic language hides the fundamental dynamics. I think in this case it was the last straw that breaks the illusion that "social" apps are based on IRL 1:1 interactions. TikTok is an app designed around capturing an audience with a series of 30 second videos.
