> that at most uses your buying history to suggest you books to buy

There you have it. And beyond that, the corporation will sell the data to whoever if profitable. They will abuse them any time there is anything to gain.

I think getting recommendation of similar books to read is a feature rathen than a bug. If you ask your friend to recommend a book the first question they'll usually ask is 'what kinds of book do you like'. Either that or you get recommended whatever NYTimes says is the bestseller (which may not match your taste).

There you have it, what is the horrible thing about a company suggesting you books?

They won't sell it because it is their advantage.

> uses your buying history to suggest you books to buy

So they do care and intend to use the information to practice psychological tricks and deception to make me buy more things (probably not just books) and also sell it to others who want to do the same. No thanks!

Yeah, right. So what do you rather have when you get into a website, tailored recommendations or generic ones which do not apply to you?

I rather have targeted adds of things that I might need than porn and poker adds.

In order of preference:

1. No recommendations

2. Generic recommendations

3. Tailored recommendations

4. Paid ads

I’ll always use an ad blocker to aim for (1) anyway, but shouldn’t have to rely on that.
