The thing is, we've established that trying to invade us and found a colony as a path to getting more 'senator' influence within the Salamander government's broader structure is
fucking risky, to put it mildly. The specific bozos who attacked us just reached in and got their hand mauled, and by the time anyone else manages to mobilize a stronger expedition we'll have completed our current cycle of adapting weapons capable of fighting back against their technology and be a lot better prepared for their capabilities.
It's not
impossible that they'll just endlessly keep trying to find ways to subtly neocolonialize us, but we can't actually prevent that just by fighting the
current land expeditionary force of the current batch of corporate raiders to the death. Like, seriously, how does refusing this peace treaty actually stop them from doing any of this anyway? The only benefit to us in terms of deterring future efforts to subjugate us is that we'll have shown we're willing to resist to insane extents and use extremely disproportionate fanatical or overpowered weapons to fight back. But we've already proven that based on our willingness to repeatedly nuke our own planet to blow up individual Alien Enemy tanks.
We've pretty much maxed out what we can gain from this war in terms of captured enemy tech, and in terms of establishing our own "badassoftheweek.com" reputation as a species of madlads not to be tangled with lightly or casually despite our inferior technology. At this point, our future prospects as a species unlikely to be conquered would benefit far more from us beginning to be able to systematically contact the wider galaxy, learn how their technology works, and identify the big polities so we can contact them and try to play them off against each other rather than being a patsy for one or another of them.
That it is likely that they will try to ignore the fact they indirectly tried to colonialize us and fugue out a different way to do it, you can't be a friend of those kinds of Nations we have to find real friends.
The task of finding real friends will not be simplified by us having no peaceful outlet to the wider galaxy apart from weird shady shadowports where Salamander corporations can probably just literally pay the local gangs of pirates to hang around and shoot our ambassadors for the bounties.
Meiji Japan did not get particularly favorable trade deals with Western nations;
nevertheless, they wound up having to make those trade deals as a necessary part of industrializing and becoming a relevant power capable of defending themselves.
So that information has made it were this company is more trustworthy than that government of nothing because at least this company is likely to actually do something then nothing.
I don't think it's that simple. If their government authorities actually make an agreement, we have no reason to expect the agreement to be reneged on. At the same time, they're going to default to delegating a lot of power to the company, so they
won't make agreements without a strong reason or unless it's easy for them to cooperate.
