This is just propaganda. The title is misleading, the text itself is sensationalist and over promotting their own product. Git authors are simply names associated to commits, it's not supposed to authenticate anyone, so talking "forgery" is just nonsense. Any repository owners worried about the authenticity of the commits should allow only signed commits. This is available in all major git platforms AFAIK.
