1. It's obvious clickbait - "secret" brands - how salacious! Yeah, as though a company wants to keep things it sells secret.
2. Each time you click on a link from the Quartz article, you are given a url with a link tracker tag. For example, for the Arabella brand, you get:
16352060011?tag=quartz07-20
So basically someone sat there behind a computer, authoring an article while using words like, "expose" and "clandestine" brands, and "attacking small brands," while simultaneously setting up ad links on their Amazon account so that they would make money from Amazon every time someone clicked on said brands.
Now that is journalistic integrity at its finest, and emblematic of the world of manipulating people's fears and worries for profit that we live in.
