If I was Bethesda, what I would do is refund everyone,, close down 76 servers and just scrap the whole online thing. I would rework 76 making it a single player experience, and add it as a Fallout 4 expansion for $5. The would recover some credibility and learn the lesson at the same time.
Rework as in, add Human NPCs, still leave some holotapes and terminals to help tell a story, but not make neither of them a priority to tell a story or start quests. Remove the flying cerberus-thing boss, and what ever else needs to be flipped to make the game better.
