according to the manual, Talon Company have been hired to keep the wasteland a violent and lawless place, and stop society from being rebuilt. This brings them into conflict with the Regulators, the Rangers, the freed slaves, the Brotherwood, and even the Outcasts. and since the Super Muties attack anyone on sight, as do the Raiders, that kind of covers nearly every faction.
That's also why they go after you for such ridiculous things as they do. Acts of decency, kindness, and altruism are the first stepping stones on a path that eventually leads to the restoration of civilization. Daniel Littlehorn, for his own sick reasons, seeks to prevent this.
Thinking about this for the last couple of days, (I know, right?) it occurs to me that the Talons and whoever has hired them to keep the anarchy boiling are actually some of the worst villains in the wasteland.
What a horrible and crazy thing to do. If this is their project, it's an extra shame that more wasn't done with the story. It's a lot more evil than the random attackers and monsters, and would be a point of agreement for the BOS and the Enclave to want to defeat them. If it were exposed, at least...
Say, maybe the Enclave are secretly backing them so their version of "Law and Order" will look more attractive, or maybe the BOS back in California are doing it to keep Lyons from being successful in his unsanctioned agenda and becoming a leader on the East Coast.
The Talon's attacks would be so great if they slowly ramped up in scope and planning, and also if you could either join them, pay them, or take out their nasty customers after some detective work.
