I think it did have to be like this in software.
As with socio-economic systems, the outcome was more some mathematical integral of the behaviors of all participants than some driving force.
To me in this moment, "big corps" are more a consequence of what we are - first personally, then amplified collectively - than some evil descending from above. They represent/reflect a fundamental lying/cheating/deceit of the vast majority of individuals ("when no one's looking").
I suppose one could argue they foster even more of such in subsequent generations, but where did they come from in the first place but this species as an interactive whole?
So of *course* the software situation had to go more the direction of big corps lording it over idiots, because as a species we're mostly idiots, imagining personal gain more in hidden subterfuge than in loving our neighbors as ourselves. It's this weird upside-down-ness where greater idiocy sinks to the bottom, and the bottom is from whence idiots are ruled.
Something like that. :-)
I'm gonna go to an unpopular (again, due to majority idiocy) analogy, and put it in your words:
"No! It didn't have to be like this. The Ten Commandments were meant to empower us, eliminate the destructive aspects of our lives, enrich us instead of hindering us."
And yet here we are....
Yeah, I know... I'm being quite the downer, here. *But* I do believe there's a way out of the madness - but within where the errant (let's call it..) "pseudo I" lives and reigns.
And you can bet your proverbial "sweet bippy" it ain't goin' down without a tooth and snail-mail fight! :-)
