Do you seriously believe that this data is “the most relevant thing possible” to assert the claims “Elixir is past its peak” and “is all down hill from here”?

I am not refuting the data, I am refuting the flawed conclusions you are drawing from it. You are taking the decline in usage of one service as an overall indicator of the community. I provided a possible explanation. I mentioned the GitHub ranks as counter evidence. But way to go on the ad-hominem.
