The creature it refers to pretty universally considered repulsive. I'm no psychologist or anything, but I would expect that to have an undue influence on even the most rational person.
I don't know; do you want to build services that depend on random hardware on residential internet connections, hoping they stay online, while exposing metadata to the entire WAN or slowing it down with some kind of mixnet protocol?
To me, edge networks make more sense. Distribute your services across datacenters close to your users.
What I don't like about P2P is that it depends on peers being online at the same time, and it exposes metadata to the whole network instead of only law enforcement and sophisticated / well-funded attackers.
