> Unilaterally imposing unfair trading conditions on other online classified ads service providers who advertise on Meta's platforms, in particular on its very popular social networks Facebook and Instagram. This allows Meta to use ads-related data generated by other advertisers for the sole benefit of Facebook Marketplace.
Consider this:
- A local marketplace AcmeShop wants to advertise itself on Facebook, paying Facebook for ads.
- The only practical way to do so requires AcmeShop to install Facebook's tracking on their website. The tracking is always dual purpose: on the one hand, it gives AcmeShop data on conversion from their ads (which is vital for AcmeShop), but on the other it also gives Facebook data about AcmeShop users.
- Alice wants to buy a used 3D printer. She goes to AcmeShop, searches for 3D printers, checks a few listings out, but doesn't buy anything.
- Alice opens Facebook. At this point, Facebook registered Alice's visit to AcmeShop 3D printer listings, so of course they serve ads for 3D printers selling on Facebook Marketplace.
- Alice buys a used 3D printer from Facebook Marketplace, cutting AcmeShop out.
AcmeShop has a tough choice: they either advertise on Facebook, pay Facebook, and help Facebook to undermine their own business, or they forgo Facebook as a marketing channel altogether.
Usually different parts of this scenario are discussed in isolation (performance marketing, user tracking, privacy on Facebook, etc.), obscuring the larger picture. I don't see how Facebook's behaviour taken as a whole is anything but predatory and abusive of their position.
