Why don't ISPs peer with everyone?

I agree, HE's peering policy makes them an attractive transit provider. 

However, money and strategy still come into play here. 

For example, ISP Z will think "I need some peering and transit. But if I get HE transit then some people may not peer with me at X-exchange because they will already see my routes via their HE peering" So then they get some transit from a network who is useless with their settlement free peering, then get the peers on the X-exchange and only when they are happily peered will they go to HE.

FWIW, Hurricane Electric has an aggressively open peering policy and we
will peer with anyone who is willing to peer at any exchange where we are
connected. We believe as stated by Rucas that this only serves to enhance
the internet experience for our customers as well as our peers.

So far, it seems to be working pretty well for us. I encourage others to follow
our lead in this regard as it truly does make a more functional internet.
