I appreciate the additional information, however, a link found in the codeberg link you provided leads to this comment from earnest:
The up arrow is the equivalent of a boost on Mastodon, adding to favorites is represented by a star. The down arrow is equivalent to the Dislike button on Lemmy and Friendica, Mastodon probably doesn’t have an equivalent (Dislike will be federated this week). Compared to Lemmy, it works a little differently, as the up arrow there is the equivalent of a favorite.
The comment activity can be checked by expanding the “more” menu and selecting “activity”
This seems to imply that downvotes (reduces) are federated. (And notably, upvotes are now “stars” “boosts” are, uh, “boosts”; this was changed since the linked comment was made)
Or am I totally missing something? That’s always and option.
What’s bad faith about my argument? There’s only two options: You believe what you typed and that it’s impossible to make this mistake, or that you were using hyperbole, and you acknowledge that it is possible to make this mistake. These two options are both mutually exclusive and binary-- there can be no other stances. (and notably you haven’t actually clarified which one you believe.)
I didn’t make you choose to defend a poorly thought out stance. That’s on you.
