> Zuckerberg was specifically talking about cloud infrastructure software, but the same point applies to AI capabilities as well: Meta isn’t selling its capabilities; rather, it sells a canvas for users to put whatever content they desire, and to consume the content created by other users. It follows, then, that Meta ought to be fairly agnostic about how and where that content is created; by extension, if Meta were to open source its content creation models, the most obvious place where the content of those models would be published is on Meta platforms. To put it another way, Meta’s entire business is predicated on content being a commodity; making creation into a commodity as well simply provides more grist for the mill.
