While it's true that Google and the like benefit from closed or partially closed data ecosystems and formats, as I've pointed out in another comment elsewhere in this thread [0], they've at least been pushing for the development and adoption of linked data formats like JSON-LD and vocabularies like schema.org, and they're using both of those pretty extensively in products like search and Gmail.
It's a far cry from things like Solid's vision of a fully decentralized web of linked data, but at least it's something.
