That’s an unfair conclusion. Those examples were pretty specific and I, at least, see no reason to generalize (except maybe the insurance one), except perhaps along the lines of “serving exploitative monopolies is bad”
What I meant is that you can find an example in nearly every business of some person (or group of people) getting "screwed over", which is of course subjective. So subjectively, you could make the case that every business is "exploitative" (like the other replier who claims every capitalistic business is exploitative).
In fairness, there is no ethical consumption under capitalism. If you take that to its logical conclusion, then there is no ethical software development that supports capitalist endeavors.
