The file was widely shared on Google Drive and linked to from a public twitter message— it was very much not a personal file. And the title literally was, “An Effective Treatment for Coronavirus” referring to hydroxychloroquine. Google’s doing its part to purge pandemic misinformation and prevent harm. The authoring “doctor,” as far as I can tell has never had postgraduate medical training and cannot practice medicine without supervision, is trying to achieve writing a document with a title like that I don’t know.
