Metcalfe's law: "*value of a network is proportional to the square of the
number of connected users of the system*." The problem with a walled garden
is that it can only grow as large as the walls allow.

Point taken, but I actually think it is more of a Christensen-style disruption
where the 'lessor technology' outstrips the more sophisticated one because
it finds/creates a new market that values that new technology for what it
is and cares less about the ways it may be 'lessor.'
