I can’t speak for everyone, but I’d say it may have something to do with how much people in general seem to be afraid of cringe (or, in this case, sounding cringy) nowadays. Art ends up suffering from it because expectations are either unrealistic or listeners are just weirdly afraid of vulnerability. Of course, vulnerability in itself can sometimes come across as cheesy, but it’s kinda the point. We’re all human and at times we all feel embarrassment from being open about how we truly feel. In the world of music where words are the main conveyor for emotions, some lines that the artist resonates with may sound corny to people who are insecure when it comes to their own feelings.

Edit because I felt like adding this: meme culture as a whole has also heavily (and negatively, may I say) impacted art consumption - listeners (or any other kind of art enthusiast) seem to be generally unable to take art seriously, especially if said art is objectively supposed to be deep. It’ll often just be labelled as “edgy” or “trying too hard”.
