I've read most of the comments in the original announcement post and think there are a lot of misconceptions. It's nice to read a post where somebody tries to understand what's really going on, so thank you for this.
I think one really important point not being discussed is the question of "how many votes does an average user cast per day?". Let's face it: a lot of users, probably most, don't understand the workings of the platform on a deep level, and just go with "what's easiest". Nothing wrong with that. I would also hazard a guess that on a statistical level, way too many people are close to 100% of the voting power most of the time. If this change lowers that number (and I think it probably will), the balance of power between bots and normal users is automatically shifted towards humans, like most users probably would like it to be.
For the minority reading this and the original post, not much is changed really, as you can just have things as they were by using the slider. Having said that, it would be nice to have a default setting for the upvote power, as fiddling around with the slider is extra work...
Well, I tried to answer something like that.
