They just won in court like two days ago against the FTC to go forward with Within's acquisition.
The Within case isn't informative, IMO -- Within wasn't building social media applications. It was more a case of an acquihire. The VR ecosystem is too early to have an Instagram/WhatsApp moment, yet.
I brought up Within because it was talked about a lot on fin-Twit as proof/sign they can't M&A anymore.
