I find it serves one better to deal with feelings directly. Going on such a long roundabout is a distraction. Do we really care about how large companies deal with their problems? Are we running one, do they depend on our judgment? I think not.
So, the more straightforward way is to realize that one has been fucked over. At first it doesn't matter who's responsible for that, just the fact that one feels that it happened, and that it feels like shit. Talking to people about that helps. It someone is worth their salt, they'll tell that this has always been the case - the one that cares about a person the most, and especially the one that can do the most, is the person themselves. And another important realization is that most of the time, this doesn't happen because of specific cruelty - most of the time, it's ignorance. The other party didn't care to consider the impact of their act, and that is normal. There's not enough energy to care about all. And even if we care, sometimes things must be done. Or we need to take part, even if we know the impact and don't want that.
I do believe that this all doesn't need to make one jaded and cynical all the time, about life and people. In fact I believe the opposite: that one needs to find a way to love all this, in spite of all of these things working in such a way. After all, to love, one needs to know. Because if one doesn't know, they don't know what they love in the first place.
