This is the same kind of "proof" as naming Sean Patterson "a cheap actors" based on his cooking photo (he mentioned cooking as a one of his hobbies on a social net and uploaded a photo)
Really?
Really.
Sean Patterson is not fulltime Worldcore employee and so what? We live in the digital age and you don't have to work 8/5 for a single company.
And we all know that Sean is also an evangelist and co-founder in few projects. "Actors" never have MBA and acting in movies instead of creating marketing strategies.
Marina simply doesn't know what "a partner" or "associated partner" is. For example in my company our HR-director also is "an associated partner" which means she has her own recruiting company while performing some tasks for our company. As I see the Sean Patterson's position he's an associated marketing director for Worldcore - nothing bad at all and it doesn't worth building any conspiracy theories.
