More accurate terms for one-sided business information?

The expressions such as "one-sided", "misleading", "just marketing" and "flawed" are more neutral and casual to more extreme terms such as "propaganda", "brainwash" and "wrong". I want to learn very selective terms to describe official material such as annual letters, reports and news carrying very little value in finance and business where information can be hard to understand without being an insider or experienced professional, potentially written in a language that a minority can only understand.
