If people are using "dislike" to indicate that they're not interested in content, particularly in a context in which there are few other ways to do so, then that is what the button means.
You might extend that more broadly to any aspect of a UI/UX.
In a past life I designed some elements of a content moderation / feedback system. Among the more amusing aspects of that was encountering people who told me that I was using the system I'd designed wrong.
Designers may have an intention. People will apply their own needs and usage to features, in the spirit of desire paths.
