...There is significant additional risk placed on the end customer for very little benefit. And the fact that your signature advertises 3 companies, two of which don't exist and 1 which doesn't like resellers really doesn't add weight to your argument.
The signature is old, it only shows that I don't care about an update...
If they don't like us anymore as reseller I am pretty sure Jihan would have told me
We are longer in the business than all existing producers or other resellers (afaik).
So the opposite of what you say is true, we add a layer of security.
BTW: you link to a overpriced R-Pi2 set, while the R-Pi2 is not even supported atm.
