The source code for Lemmy is free for all to view and modify, there will be no authoritarianism... And if it were to happen all of Lemmy administrators would either refuse the upgrade and stay retrograde, or quickly fork. The devs don't really have total control of thousands of servers to have free reign to do stuff like reddit corp does.

I'm all for vote privacy in the UI. There are just too many downsides to public votes, and not as much weight to the positives in my opinion. People should not be afraid of backlash from down voting if a post does not contribute, it'll only create echo chambers/ unchallenged groupthink.
