disconnected autonomous systems

I've found there are many providers that have completely disconnected
autonomous systems.  For example Yipes (6517) uses L3 on the west coast
and Williams on the east coast.
66.7.129.0/24 is advertised under their AS through WCG and
209.213.209.0/24 is advertised under their AS through L3.

And the number of connected autonomous systems with de-aggregated
prefixes appears to be even more common than a disconnected AS.

It would seem that many (most?) network operators are just ignoring the
more vocal opinions on NANOG.
