They're winning entertainment and for some people pure entertainment is enough.

Sometimes I read to learn, sometimes for fun, sometimes for other reasons.

For those people the act of just reading it and "enjoying" the experience and story is what they "win".

Sure, theyre* toxic, bad, poorly written, whatever other adjectives people who dislike them throw at them, but they're obviously chaotic and entertaining enough for those who enjoy them.

Same as reality TV, or poorly written fanfiction, or janky video games.
