No, it's not simply belief... It is well documented, through multiple series of court actions, fillings, public & private investigations, & leaked information that, at the very least, a third of what we call corporate media personalities (ie celebrities) have stipulations within contracts for assigned PR groups to act as handlers. It's likely more as handlers and enforcement happen through PR firms. PR means Public Relations and its literally the modern, rebranded name for propaganda. These enforcers and handlers are all connected to the same small number of large, multinational corporations through previous or current jobs.

Heads of corporations are part of the funding oligarchy, the IMF... Who directs policy through central planning, by direct appointments of aligned ideological advocates and through subsidies multinational NGOs like the Bilderburgs & WEF, WHO.. Its doubtful the Board of executives they have the same type of handlers, but they do have PR representation and donate money to pay for other handlers instead of paying taxes.

Pasternak did not "may have"... he worked in the Canadian DND DCIEM and DRDC... The Canadian equivalent of the CIA/DOD/DAPRA projects.
