I agree. As long as anonymous voting doesn’t cause obvious trolling/spam issues, it should be preferred.
One of the reasons I’ve always found Facebook off-putting and never used it (even before learning about the shady practices) are the very visible votes. I tend to overanalyse any reaction and would judge people based on their votes on my posts, even if I consciously tried to avoid it. Similarly, I imagine some other people would do the same and I’d feel like I’m under surveillance.
