Something worth noting is that this is yet another example of how the patriarchy hurts people. She felt that her image on Instagram was so important that she took risks which ultimately lead to her death. She doesn't have to be an idiot to have this happen, I've done tonnes of stupid dangerous stuff in my life and I'm fairly sure everyone else here can think of a few things that could have gone wrong.
The algorithm of something like Instagram is built around enhancing use of the platform. This is the same fundamental motivation as tobacco companies or gambling companies. Your continued use of the product is essential, even if it is harmful to your health. So they design their product to enhance it's addictiveness and market to people who are vulnerable, say younger women for example, and boom, revenue.
Meta has a meaningful hand in this type of situation. The same goes for all the other attention economy companies. Their product doesn't have to be harmful but it is way more profitable if harm is not a consideration.
