Erm, no - nothing I just said is about expressive a beef.
It’s just a description of Facebook’s core business.
If Apple does use ‘sweatshops’, which they clearly do to some extent, that is a marginal part of their business, and not part of their business model at all.
Selling Ads is what Facebook gets paid for. Targetting ads is why they can charge a premium for those ads. Keeping users engaged to content is how they reliably deliver a large volume of ads.
This is their business.
