I've learned how to fix my own appliances from online videos, stayed connected with friends through email, found stuff to do and avoided getting lost in unfamiliar cities through navigation, unwound with games, discovered new music and shared my music with others. All of that was because of or mediated by software. Could I have done it without, maybe. But I did use software for it, and tech deserves credit for that.
Maybe we need antitrust action just so we can better separate the “good” software companies from the “bad” ones.
But I think that the problem is mostly orthogonal to technology. Monopolistic megacorporations in any area are rife with problems. Look at Walmart, Nestlé, Shell, Comcast, etc.
Tech companies are particularly prone to this because information naturally lends itself to economies of scale, and economies of scale are fundamentally anti-competitive.
But it's the consolidation that's the problem, not the tech itself.
But do they find it in tech? I could understand if we were talking about doctors, firemen, artists, etc. But tech work is mostly just companies trying to push products. This isn't really evil or good, it's just economics. A lot of tech companies seem to attempt to adopt language which suggests they're doing good, but I couldn't name very many which do something other than push products. I can't remember what language they used years ago when I worked at the apple store, but it was something like "enriching lives." And a lot of the employees seemed to really believe it. Yes, if you just buy a mac rather than some other computer, your life will be "enriched."
I'm not trying to be cynical; I definitely think there are some tech companies which do objective good, but these companies are in the vast minority of the tech field. If most people in tech sought "meaning" then the field would suddenly become extremely crowded around the few companies which actually produce good for the world.
