Yeh it's pretty clearly not sincere in voice. Seems like by saying 'not satire' they're trying to avoid people thinking they mean the content of what the article describes isn't sincerely true, but given how it's written, it's hard to conclude the author cheering on from the sidelines. Te nonchalance and unaffected language when discussing a travesty seems pretty clearly to be a device used for effect which frankly is pretty close to what gets called satire.
