I know in HN there is a big "personalized advertising" is bad sentiment, but I don't get what the problem is.

I mean, if I am looking for a notebook, I rather have FB/IG (or Google or whatever), show me adds of a notebook that I might end up buying, instead of the generic poker/porn adds that we had on the beginning of the internet.

It is almost impossible to have a free internet without ads. So on one side, people want everything free, on the other side, we don't want ads, so there is a clear problem here.

Can someone explain to me what the problem is? Honest question. Thanks.

Problem is not the "personalized advertising" alone, it is more dangerous when also combined with "bidding". When those two combined, you are most likely to see ads with bigger profit margins than small profit margins.

Let's say you are looking for a notebook, you are assigned to "notebook seeking" cohort. You will see "notebook ads". But the ads you will see will be the ones most profitable for your cohort.

For simplicity, let's say cohort is 100 people; if there is a one person in this cohort that is the target of an overpriced, low quality, drop shipped product, with huge margin, rest of the 99 people will be bombarded with that ad.
