These are tough questions but the suggested answers are pretty evasive and generic. They are essentially refusing to answer the question at all.
Its ok to refuse to answer a question but realize that most investors will recognize the evasion and it will turn off a good portion of them.
If your company is doing so well and is so hot that you can afford to turn off investors with evasive non-answers, you can afford to give everyone all the information and the answers wont hurt you. Conversely if you aren’t beating investors off with a stick and you give evasive answers, you are thinning out an already thin herd.
A relationship that begins with full transparency up front is always preferable in my book.
