Yeah. It's really poor musical analysis in general, and my ears just don't agree. For example "Come as you are"- it's really hard not to hear that as functionally in a minor mode.

Also, there's nothing particularly unusual about not having any minor chords. In fact, here's a thing that may surprise some people: most African music for example has no minor chords of any kind, and we're not talking about power chords etc just only major and no minor triads. In African music it's really common to have the first inversion of the 4th degree triad function as the relative minor (so in the key of C that would be A-C-F instead of A-C-E).
