no, i do not think this is, even remotely, a conspiracy.

I think the similarity in the note combinations is due to the fact that there are only so many notes, and the originality behind those that choose the notes may be a factor as well, and the combination of a few notes that sounds good, if a company wanta a new sound they probably say, 'something like nbc', this is more of a realistic explanation, if you can prove that those notes in peticular have more power over the frequency of the human brain that would be a different story.
