All you need to do is look at the post from a federated instance running software that doesn't hide the information. Here is a link to your post from my instance, which shows upvote info: https://fedia.io/m/fediverse@lemmy.world/t/1097629/Lemmy-devs-are-considering-making-all-votes-public-have-your/comment/6869259/favourites
To view down votes, they might need to host their own instance? I don't know offhand of another software that shows downvote information, but even though Mbin does not show it, I think it should still be accessible if you're running the instance yourself and looking directly at the database.
I'd be curious to know where that expectation is coming from. On average I'd expect a majority of folks have that expectation carried over from Reddit. Another poster somewhere mentioned that there are several other social media platforms that don't have private voting, and I wonder if the expectations would be different from people who came from those.
Personally I think the transparency on votes here has been refreshing and am sad to see platforms pushing to make it private. But then, I grew up in a time before Facebook, when it was understood that you used a pseudonym, not your real identity, and needed to be careful about what you chose to share on the Internet. If you had concerns about being judged for a specific opinion or a hobby or whatever, you could just make a separate account for those topics. Kind of like how some folks only keep a Reddit account around these days for porn.
