It’s not about insecurity - it’s more like a user will accidentally click on the link, end up on the company’s site, not realise they’ve left the news site, be confused as to why the news site is trying so hard to sell them a dishwasher, not remember they were just reading an article about them, and will be scared and alienated.

Oh my god, the horror! The user will be confused, not remember, and they will be gasp scared? Alienated?? After accidentally clicking a link??? Jesus Christ the internet is such a scary place.
