When people complain about ppl crying online

I see so many people hating on people posting videos of themselves crying online. I dont get the issue, just scrolll past the video, not every video out their is going to be for you. Sometimes people post themselves crying because its significant to the context of the video. For example, i saw a video of a girl who was displaying the conditions of the mental hospital she had to stay in and she showed a video of her crying to show her distress, to show the hospital was bad.
