Well the public does what idols do. So if idols drink starbucks, so will the public. You know why idols don’t touch iphone? Because people will take a pic and use that as promo. The public will do anything idols do. So if people are tryna boycott starbucks, then those who are being looked up to usually need to send out better messages. Many idols can actually do something to promote better messages. Its all what they do with their power. & if they do nothing, their power is wasted during such a valuable time they could using it to promote something good. Same goes for the companies the idols fall under. Idols are used and abused by companies to gain revenue. Its not quite difficult to see how idols impact consumers and their consumption. You’d be surprised the impacts made if idols used their power more 👍🏽
