Remember that Meta had launched a chatbot for summarizing academic journals, including medical research, about two weeks before ChatGPT. They strongly indicated it was an experiment but the critics chewed it up so hard that Meta took it down within a few days.

I think they realized that being a direct competitor to ChatGPT has very low chance of traction, but there are many adjacent fields worth pursuing. Think whatever you will about the business, hey my account has been abandoned for years, but there are still many intelligent and motivated people working there.
