ii) I would disagree on this. Meta is king of low value ads. Google is great at targeted ads, but sometimes you want something to reach as many eyes as possible, as cheaply as possible.

They've barely avoided many of the dark patterns like chumboxes and forced repetition of screens, just because they have enough people scrolling through it. Of course, there's other dark patterns here, but I give them a B+ for low value ads.

The marketplaces and events still provide massive value to the world, for free, as long as they lasted. In the end, it's nearly a trillion dollar company, which is a remarkable thing to build on low value ads.
