I think that's their point. If Google or Facebook had stayed with a Valve-sized team and stuck to their knitting, would they really have made any less money?

Would this preclude buying Instagram? That was considered expensive at the time, but I think was a great buy for them and is a significant part of keeping Facebook competitive now and for the next half-decade.

Facebook marketplace and groups are other successful (IMO) sub-products that might not get built if "stick to your knitting" was the mantra.

both had slump but I think Facebook has been much better shape after Zuck did layoffs and pivoted away from metaverse. Llama and Meta Smart Glasses both feel like groundbreaking products.
