It moves the monopoly to the IXP operator!

When everyone is in one facility (or at least building) it is
typically easy to get low priced (although maybe not low enough,
see other posts in this thread) cross connects.  It's common to see
a pair of public peers fill up a significant part of their port,
and then move to a private peering model getting off the IXP and
onto glass directly.

When the IXP is distributed, this becomes glass between buildings,
often requiring yet another supplier as well.  The MRCs are higher
making the justification to move off harder.  What happens is rather
than moving off to glass, they have to buy faster/more ports from
the IXP and move the traffic over the IXP.

The IXP becomes the go-to monopoly as a result.

Now, perhaps IXP's are more benevolent than data center opertors,
and this is a good trade.  I think one thing the presentation was
asking people to do was step back, look at the situation, and
reevaluate that particular tradeoff.
