Of the top of my head:

* Journalism no longer prioritizing truth, but eyeballs/clicks. * Immense user frustration * Waste of bandwidth (energy costs, etc)

I bet there are many more.

Even without targeted advertising journalism would still use advertising, they'd just make way less money.

I agree with your first part, but the second part isn't true if it were prohibited to do targeted advertising for everyone.

It's an arms race, you only earn less without targeting when your competitors are targeting. When all advertising is equally poorly targeted, everyone's getting their fair share of the available advertising dollars.

The collection, purchase, sale, and distribution of sensitive user information without the users consent.

If it had a bigger clearer warning - like the cookie banner, then there'd be no harm?

Insatiable consumerism and discontentedness
