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.
