The incentive to go into all these wild possibilities is pretty strong -- companies must list everything that might ever conceivably happen so that nobody can point a finger at them later and say that they forgot to include something so now they're gonna be sued for millions.

This is the same reason corporate PR statements sound the way they do, and it's the same reason politicians speak the way they do. People say they want openness and honesty, but then they punish businesses and politicians for even the slightest offense. Because of those mixed and contradictory incentives, this is the kind of communication we end up with.
