Protecting the brand is just as important as the branding process itself. As soon as some negative issue arises with an org piggybacking on Maidsafe. Maidsafe, the farmers, investors, devs, et al pay the price. Maidsafe needs to set guidelines for who and how its "EXPENSIVE" branding can be used.
PDC should not be allowed to use this and Maidsafe should not give them permission.
If a logo needs to be created for complimentary technologies that are built for Maidsafe - similiar to "powered by Intel" then lets do it. But ir needs to be clear this is not Maidsafe.
