The PI space came from the space ARIN had for PA assignments. It was sub-allocating
space that had been allocated to it. The purpose of the allocation changed.

Squatting has been going on for as long as IPv4 has existed. There have always been
people not wanting to do paperwork to get space.
Comcast, Microsoft, Facebook all dealt with not having enough IPv4 for their internal
purposes. They all moved or are moving to IPv6-only for internal communications. For
the machines that need to talk to the IPv4 Internet they use host based IPv4aas mechanisms.
You don’t even need to have IPv6 upstream links. You can translate all the outbound traffic
DS-Lite on the host or host based 464XLAT both work for this purpose. There are other
mechanisms that work at the host level as well.
This isn’t a problem ARIN needs to solve.
