As I said tgo someone else above, I think this is a cop-out.

If Fedi's features suck expressing support by giving them a pass on implementation or privacy issues isn't helpful either to improve the issues or in the process of making open alternatives more popular.

For the record, nothing is being gained here in terms of features. Up/downvoting already doesn't do what it's supposed to do and it already isn't reliable or consistent across instances/services pretty much at all. Being public is the cherry on top of the "wanted to look like we have the feature but we really, really don't" sundae.
