I agree in a sense, but it depends on whether we're talking about disrupting the current incumbants or about disrupting the mechanisms of centralisation itself.

I agree in a sense, but it depends on whether we're talking about disrupting the current incumbants or about disrupting the mechanisms of centralisation itself. Microsoft's PC has disrupted IBM and created a new "monopoly". Same with the web and mobile platforms, which are now dominated by a handful of oligopolists that appear stronger than everything seen before. I think incumbants can always be disrupted, but can they be replaced with something structurally less prone to centralised control or are we just headed for the next cycle of disruption and re-centralisation of power?
