Disagree - when a company responds with mealy-mouthed corporate gruel, designed in bad faith to obfuscate and distract, there should be no obligation on the part of the investigator to propagate it.
Ironic how two opinions can be completely opposite, yet both valid and well-founded, and unverifiable at the same time.
I personally believe that journalists should do their job and decide what gets written and how, and save readers from drowning in information we have too much of anyway.
Why not both? Have the reporter editorialize in the article itself but link to sources and references including the full response as a way of showing their work and letting readers validate.
