SEC 17b regulates disclosures, not stockholders. Even a farmer, heavily invested in Apple(s), can stand in the supermarket--on its payroll--and sell them: Badge displayed. Amendment One applies, and then there is SEC 17b itself: Which is not about Supermarkets at all(?)! Mostly the matter of paid or unpaid promotions is evidence of Company progress, and CEO directed, (alluding to the progress, apparent now to others).
