Why do you think there is no large open community project around knowledge graphs comparable to Freebase ?

Freebase (2007–2016) was a pioneering open, community-driven knowledge graph that allowed anyone to collaboratively create, edit, and query structured data through tools such as the Metaweb Query Language (MQL) and a user-friendly graphical interface. In contrast, today’s open knowledge graph projects such as Wikidata and DBpedia provide collaborative data curation but they do not allow any individual to build and share personalized knowledge graphs with an easy query language and GUI environment. Moreover most prominent knowledge graphs (e.g., Google Knowledge Graph, Amazon Product Graph, Facebook’s Graph) are proprietary and closed.
Why do you think there is no large open community project around knowledge graphs comparable to Freebase ? Do you envisage that emerging approaches such as Graph RAG (Retrieval-Augmented Generation with Graphs), which aim to bridge the semantic gap between unstructured and structured knowledge, could assist to change this landscape?
