Wait, I need to ask about the sample data & methodology here: - these 100 users they asked, were they already frequent users of TikTok and Instagram reels?

This experiment makes no sense if users spent a lot of time training the TikTok algorithm, prior to running the experiment while they didn't train the Instagram Reels algorithm? Of course the results are more interesting and less generic if they had used TikTok a lot before...?
