One thing to consider is that there is now a lot of Go out there, especially in the ops world thanks to k8s, Terraform, etc. A lot of people have put a lot of effort into learning it, and may have even built their career around it. So it's not surprising (even if it's a little sad) that people react very strongly to criticism of it. You sometimes see similar reactions to criticism of JS.

Just this week I've been dealing with a random crash when we run `terraform plan` which turned out to be a data race in Terraform itself. I honestly can't understand why something like Terraform, dealing with critical infrastructure, secrets, etc, would be built in a language like Go, apart from that all the other ops-adjacent stuff was being built in Go. The discussion in TFA about not selecting your tools solely based on what other companies are using is cogent.
