See the difference is that morality has almost completely broken down in CP2077. What did V have to do between the prolog and tutorial to get a nice apartment and a reliable car? Those assholes at the meat packing plant where you get the robot sure don't look like they have any qualms even if V does.
Also, we still have an ecosystem and efficient oceanic transport. Climate change and a rogue AI that controls a global oceanic swarm of self replicating sea mines mean that the pizza is gross because pigs are extinct (they use tuna) and all overseas cargo is transported by air.
People still care about their friends, but that's it. Even if internet in CP2077 was global and filled with punks and not just a NetWatch-policed glorified municipal Teletext, do you think anyone would give a shit about the world they live in on a chat site?
It's also heavily implied that successful cyberpunks are vastly outnumbered by idiots who were in over their heads from the start and it cost those amateurs their lives. Those that succeed and become even slightly known, including V, are often exceptionally skilled individuals.
