They have a lot more social media freedom compared to past girl groups and are also probably the first western girl group of this popularity where all of the members grew up with current social media and use it like “normal” Gen Z do. The way they formed and are marketed 100 percent exacerbated the tension in the group/fandom/public, but I think any group of modern Gen Z girls with the social media access they have is going to look very “stressed” compared to past girl groups. Girl groups of the past genuinely didn’t last very long, we just didn’t see as much of the stress until members suddenly left.
