Caledon Ventures and Tlasayerlaahel are competing for the tlaospice market.
This one is pretty easy I think. It's that there's another group that may have sufficient resources make life difficult for the conqueror.
Corporations are ultimately about the bottom line. If the resource is valuable enough they might attempt to take over, but a company isn't going to pay a single credit if it doesn't feel it there's a return for it. There's examples of RL corporations getting into wars and so on over resources that may not be as profitable (look at examples of fruit companies in various countries on Earth), but such companies tend not to stay in business long or stay in the unprofitable war for long before cooler heads prevail.
Corporate war and violent action in markets is a very fateful line to cross. Once you "go there" then whatever violence you can afford becomes "okay" for everyone involved and there's usually a very rapid escalation in the level of violence as well as the areas where the violence is occurring (losing on the world? why not assassinate some enemy corporate officers on their homeworld?) That kind of violence spirals out of control and has a likelihood for becoming very unprofitable and the end result very uncertain for the corporations involved. This kind of uncertainty is an anathema to corporations, which usually like peaceful and stable conditions so they can do things like set up predictable (and therefore cheaper) supply flows and their customers are happier because consistent order fulfillment. In addition, corporate war can be disastrous for PR purposes. Some reporter or other group gets wind of the situation and starts talking about how sentient beings are dying for some corporation's profits? Consumers tend to frown on that kind of thing, especially if it is for luxury goods that are not a captive market (like addictive narcotics). Consumers pressure governments. Governments sanction corporations. It's all very bad for business.
In this case, if Caledon or Tlasayerlaahel tried something, the other probably has sufficient resources to make things very unprofitable for the other. If conditions and the two get into a "real" corporate war, the end result is that they'll probably just weaken each other to the point that other entities might come in and brush both of them aside. Ultimately, their accountants can pretty easily look at the bottom line and go, "Yeah, it's better to just compete with them through non-violent means, it's much more predictable."
Other examples are more difficult of low TL non-victimization are harder to justify. Nihilisitc wildcards like a bunch of middle-aged or geriatric war veterans going through identity crisis, alternately being mercenaries, terrorists, and merchants as their sociopathic whims take them (eg, player characters) are a lot more dangerous since if things get too hot, they can just jump out and go somewhere far, far away.
