Scalability in terms of node voting.

I've stumble to a twit storm from a developer of Iota team criticizing consensus of nano. He seemed to me having a good point about nodes voting. I'm coping below the tweet that caught my attention. What you guys have to say about? Is it a issue Nano team is working on? Isn't it a issue at all?
