"It's a shame that the people who are listening to you the most are only interested in you because they want you and your peers to buy their product."
I definitely think the quote is true. My dad knew has a friend who works for one of those marketing companies so he would sometimes call to ask questions about what i had bought recently and which ads i liked and things i have seen around that seem to be popular. I dont think though that it is intrusive or anything, their goal is to make money and they are being smart by going right to their audience and asking them what they would want to buy. I dont consider it a "shame", theyre just doing their job. Yes there is too much marketed towards my age group but i would personally much rather see things that interested me than things im not interested in at all.
