@wakest @wakest maybe? Dislikes are somewhat arbitrary thing, there is no clear definition of what is dislike-able as far as I'm aware, it's up to the server, Lemmy can dislike whatever it wants (and can digest), Peertube decided that you can dislike videos, there is nothing out there that forbids disliking audio or events should any server implementation decide that this is what they want. Dislikes are also kinda abusable and not everyone wants them.
I think what I'll do is make it user-configurable, per post or per type of post, with group posts (peertube videos are technically group posts too!) defaulting to dislikes being enabled, to match the current fediverse expectations
