That's a cop-out. If there is one thing we have learned from the current generation of dominant tech services, it's that network effects can be hugely powerful in this space. A business with a strong enough network effect supporting its main product or service can, evidently, screw up in almost any other respect and still survive with its network intact and its share price untroubled. And that remains true even if those screw-ups can have catastrophic effects on many little guys who were affected.
