Counterpoint: the HTC First (aka the Facebook Phone) was >$1 USD less than a month after it debuted, and still was a gigantic flop. Facebook Portal has sold ~1 million units. Oculus has sold ~8 million units or so (all numbers based on quick googling, might be wrong). So people reject Facebook hardware all the time, and they don't actually have that much in the way of hits in the HW space.
