The fact that Weaviate only recently started calling themselves a vector database is completely irrelevant here. They had this type of vector data infrastructure before Pinecone did, and that's all that matters.
Example: I'm going to start a new company called Conifercone and do pretty much exactly what you do, but call it a "vector datastore" instead. Apparently I've now created the first ever vector datastore even though functionally I have done nothing novel.
