This is genius. Whenever a company does some fundamental discovery, you can point at some grant they once got for something vaguely adjacent and say "see! quasi-publicly funded!" and your worldview is saved.
If you want to learn, go trace how deep learning was funded. It started off with USPS.
Both things are true at the same time, and acknowledging the public foundation doesn't diminish the private achievement. It does raise a question about who should benefit from what gets built on top of it, which is what the piece is concerned with.
