I do not understand why this comment has a bad vote, hackernews looks like reddit, if a comment goes against your opinion, downvote without explaining the reasons.

The only thing I disagree with is that Facebook does make big profits from its ads, in fact it does a tough competition to google and amazon... the rest of your arguments seem correct to me... facebook doesn't feel like the home that it was before... it feels more like a newspaper, full of ads, debates, news and toxic people
