I disagree; SpaceX has a clear interest (and a well-established track record) of presenting things in a way that bolsters their image. Outside experts could provide critiques of the report: What represents bad luck, what is trivial, and what is a serious error; where is SpaceX being straightforward and where are they spinning things; where are the gaps, where are there alternative analyses of the same data, and what seems solid.
That is a big reason why journalism is important: It provides context and other voices.
