"rant"? Is that what a criticism of a technology that you like is called?

I feel your response is best summarized as: "I like Python. I've never had this problem and don't think it's a legitimate problem. Only $megacorp users have this issue, and their concerns aren't important."

If you dismiss the problem (as you've done) then you don't have to intellectually address it. The Python 2 -> 3 transition was hard for those that huge productive workloads in Python2, and this pain will have a long tail.
