Who are BFL's investors? BFL claimed they have a Venture Capital firm backing them, but won't say from which VC firm.
What they said is "It's a secret". It is a "secret" because there is none. BFL customers are investors without the rights investors have.
Being a private company (as opposed to a publicly listed one), what requirement is there that they say who their backers are? You say there aren't any backers, but provide zero proof of that too. Saying what you wish to be the case to justify your feelings towards them?
