I don't think that's true. Game developer company culture is heavily oriented towards making and selling products to consumers. They know how to make games people will pay for, and the entire business and culture revolves around that.

With Meta and other ad-driven companies, the people aren't the consumers, they're the product. The whole incentive structure and architecture of the company is fundamentally different. Think about how a company like Facebook or Google has an entire army of sales people and enormous apps like AdWords and Facebook Ads Manager that are how the company actually makes money. Game companies don't have that kind of stuff.

What they have is a bunch of programmers who know 3D rendering and networking. But Meta can simply hire those people—and game devs are used to bouncing around every couple of years—and they are. Several of my old EA coworkers are at Meta know working on it.
