I wish they would use a bit more the cooperation they got with Aubrey, but maybe be they have some kind of special agreement we are not aware and does not want to happened in a video talking about eHealth?
Yes, I get that, but Aubrey is one of the consultant of this project, beside getting paid in cash or some other form for his services, will likely get a good portion of tokens as well, so he must also have something to gain by actively promoting the project.
After all is one of the most famous scientist in this field, if he decided to work with this project it must have seen something good in it.
