The only top 20 I know that has publicly come out against it is @yabapmatt, who retains the freedom vote and ironically is #1. The other top witness that is against it is @drakos (who is now not in the top 20 - weird how that works). @thecryptodrive is hesitantly on board but wants the SPS to come from witnesses - which I totally agree with. What better way to give back to the community that supports you than by giving a meager 1% of your rewards? I think @themarkymark is also somewhat hesitant based on what I've seen in various comments the past few weeks, but then again, I could be misinterpreting what he is saying.
