Yeah it's a fine line between "insurance" and "protection".
The key distinguishing factor here is the protection pool actively seeks to invalidate bad patents. It could also lobby for patent reform. By doing so, it makes patent trolling less profitable and thereby, reduces the need for itself in the future. It's like a health insurance company funding research into perfect health and immortality (but more achievable).
