Ultimately relationships with humans are what matter and the only place we can ever really put any level of trust. Corporations themselves don't have agency or even consciousness—they are just the chaotic sum of actions by a wide range of people with different varieties and levels of power, most of whom will never know, let alone care, about you as an individual. Dystopian as that sounds, it's not really different from the natural world. The key is not to anthropomorphize an organization—companies and jobs come and go, but the reputation and relationships you build with people are what will sustain you.
"Agency" in the sense you're using it is "the capacity, condition, or state of acting or of exerting power" (Merriam Webster). It seems pretty clear that corporations have that.
As for consciousness, prove it. But first read "If Materialism Is True, the United States Is Probably Conscious": https://faculty.ucr.edu/~eschwitz/SchwitzAbs/USAconscious.ht...
Just plug in to something you like, do your best, and recognize it for what it is. You should have neither an adversarial nor misrepresented relationship. If you have it, you by definition support it.
I've had startups in the past with co-founders like this. Seemingly nice sales-guy types who turn out just to be awful people with no real respect for others or class.
I always mark the people more than the org. Do your best to work with honest good people and dividends will always be paid.
