>It’s not the job of a bug reporter to figure that out

The comment isn't blaming the reporter for not doing that.

It reads the opposite to me. I absolutely read it as "you reported this to the wrong people".

The comment isn't clear. It can be read as blaming the reporter, or it can be read as telling someone else who works on .NET (who?) to open a bug report against UCRT.

It is at the very least putting the onus on the reporter for correcting it, which is not how it should be done here.
