Probably both, it does relates back to the time and standard of reality TV and gameshows, like the point about The Weakest Link haha.
Those shows were kind of childhood nostalgia for me

but I forgot the more specific mean things, or didn't understand at the time.
I guess the demand for young people to become 'superstars' through competitions has been around for centuries. Probably more televised since the 1950s and 60s, where some'd probably be taken advantage of quite easily by companies, bigger fanbases, etc.. Regarding the style and beauty standards in the 90s and 00s, the ideal seemed more limited, and quite discriminatory towards people who didn't fit in, or at least the height of it.
Although music-related shows today are generally more considerate, I still think with these mainstream junior talent shows (even Junior Eurovision) that some could be pushing young people towards a certain image/presentation too much.
With social media, those who used these frequently in childhood tend to be more prone to certain societal pressures. I avoided my involvement in a lot, partly due to choice, and because one of my friends got into trouble with Instagram posting in primary school about 10 years ago, not even teenagers at the time.
Overall, the X Factor thing impacted several contestants, it sort of enhanced the problems of the time with image and pressure from TV 'authority' and peers, and of course, each person's approach to and tolerance of that may vary, especially when self-destructive habits are involved.
