I'd say no - not publicly, anyway. There's a real difference between platforms knowing your dislikes (fine, useful even) and broadcasting them to other users.

Here's the thing: tastes evolve. You disliked something at 18 that you'd defend at 28. Do you want that old reaction haunting you forever? Plus, once your dislikes are public, they become ammunition. People don't forget. They weaponize taste.

The deeper issue though is that platforms *want* to show this stuff because it creates engagement - debate, defensiveness, the whole social graph lighting up around conflict. That's the real agenda, not some transparency ideal.

Keep the data for recommendations. Keep it private for everyone else.
