I'm honestly curious about what is VC reasoning behind investing to decentralised networks? In my view, a company behind such a product would be inherently un-exitable.
This is a fallacious argument. It doesn't matter if some people predicted a company would fail even though it went on to succeed beyond what most people predicted, this is a rare outlier and usually the naysayers are correct, even if only because there are naysayers for literally everything.
