"the org, blaming the language".

I didn't see anywhere in the article blaming the language - can you find a quote to support your assertion?

From the article: "After two years of iteration, the code has become difficult to maintain. No one on our team is an Erlang expert, and we have had trouble debugging downtime and performance problems. So, we decided to rewrite it in Python, the de-facto language at Mixpanel."
