The author of Martini released his framework, some people in the community said it wasn't idiomatic Go, he agreed and eventually released another one called Negroni.
I don't know if he was "trashed", or whether there was a "fiasco".
Jeremy Saenz certainly remains a well respected member of the Go community.
Martini is very 'magical' and makes it hard to see exactly what's going on, making it quite unusual as a Go framework, so naturally it drew some criticisms. After some experience with the library, Jeremy realized that he actually needed a lot less to do what he wanted, so he wrote Negroni.
