Arnaldo, the maintainer of perf tooling (and with whom most users complaining 
about perf would be interacting) is one of the most responsive maintainers and 
developers i've ever seen. I have not seen him brush off a single user 
bugreport or complaint, ever - let alone be 'unhelpful' or be anti-anyone. 
Ditto for Peter.

They didnt even brush *you* off, ever.

Let me guess, you just made that argument up, right?
