If they are dumping billions into manufacturing, and selling at a loss, maybe that's a problem. If they are dumping billions in to R&D and improving the tech, then let them do it.
At some point it needs to be illegal. When a large company of 30000 employees starts wiping out entire industries with cash buffers, you can see why this is just wrong and monopolistic/oligopolistic behavior.
There's a large difference between using your profits to crush competition in another area, versus setting dollar bills on fire in the pursuit of growth.
There should be regulations around both of these, but they'll need to be different ones.
I agree that this maybe should be illegal, but on the flip what is forcing the other companies to operate at a loss? I would think the name “Facebook” backing oculus means more than a low price
This should be illegal. Amazon and Uber have wiped out small players.
