It is legal red tape, tuvok007, that had to be included to ensure folk realized things like that they did not have the right to return the tokens like you could return a toaster under consumer law.
The Madana purchase is a professional or business activity.
I have highlighted the text below from their guidelines that show that in a roundabout way.

Our invitation to acquire tokens is exclusively addressed to entrepreneurs. It is not possible for us to check whether you are actually acting in exercise of your trade, business or profession. Your confirmation that you are making the investment as part of your professional or business activity means that the legal requirements for consumer protection in e-commerce do not apply. For example, the 14-day right of withdrawal granted by law does not apply to entrepreneurs. Therefore, your purchase decision as entrepreneur is final.
