This is true, but Rob Pike has his own independent connections to Oberon. Acme and other parts of Plan 9's mouse-driven UI were greatly "inspired" by the Oberon system. Go is the secret child of Oberon-the-language and C. Before Go, Plan 9 was conceived as the secret child of Oberon-the-system and Unix.
