I think that this change has been a bit poorly communicated and thus largely misunderstood. Active users (who are thought to be the ones suffering from this change) can keep on voting just like before by changing the slider to a smaller percentage. Now I also think that Ned said something like you need some amount of Steem or Steem Power to get to use the slider, which is a bit unfortunate. Then again there is the upside of keeping the UI simpler for new users. Maybe best of both worlds could be had by having the slider as an option (off as default).

When it comes to the practical effects of the change, we need to look at what percentage the human users normally have their voting power, on average. The closer that average is to 100%, the worse off normal users are when compared to the bots (as bots can easily use all their available voting power). If this change gets the average user to use more of their voting power on average, then the bots lose some of their comparative power.

The tragedy of the failed communication in this case is that people are actually getting exactly what they want and have been asking for (less power to bots, more power to human users). Still, because the numbers are a bit complicated, there is a widespread misunderstanding and people think they are getting the exact opposite of what is actually happening. It will be really interesting to see what will actually happen, but I think that the net effect should be positive (more even distribution of Steem).
