I"d ask how they felt after sinking billions into OculusVR only for Google to slap them with Google Cardboard (and the DodoCase et al), then made another slap with Magic Leap.
Having built Cardboard myself, but used an Oculus DK1 for about 10 minutes, I can tell you for sure that even the first Oculus is a totally different order of magnitude of product compared to Cardboard-style devices. I'm not really a part of the Oculus cult of personality, I didn't back it and probably won't buy a devkit, but this is a ridiculous statement.
Oculus efforts on mobile VR appear to include much more attention, including Carmack et al campaigning to change Samsung phone hardware APIs to improve fidelity.
Magic Leap is a totally different product, AR vs VR.
Seems the appropriate thing to do would be to repay the cash as if it were a $100 investment in Facebook in 2004 - stock would be fine.
