That's ... not the normal definition of "substantial".
Your life is materially more convenient, probably much much more so. The argument here is that the small and widely distributed negatives inherent in that model affect social things that are literally "substantial" and the gain in individual convenience is a poor tradeoff.
All I mean that I can point to several specific ways in which my life is improved ("materially more convenient", if you prefer) because of the actions of these companies.
I'm not sure what specifically you mean by "small and widely distributed negatives", but the balance of convenience against cost is something that each customer decides. If being a customer of Apple, Amazon (or whoever) is perceived as a net benefit, people become a customer. If not, then they don't.
But the argument was that they "improved the world", not that they were a good cost/benefit tradeoff for each individual consumer.
One of those has to take negative externalities (aka social/legal consequences or the "small and widely distributed negatives" I was referring to) and the other does not.
You don't get a "star trek future" by trading freedom for micro-improvements in convenience.
