Good examples are movies like Sneakers or WarGames or even The Net, where some computer culture aspects are either clearly fleshed out or given attention as their own unique world that may supercede what corporate is doing or aware of. If corporate endorses it, yeah no, that's often more of a morality play.

It only bothers me when it's a documentary, but if it's fiction, well, computers and networks are mystical to most people, you don't want to disappoint them with the mundane reality. The same goes for investors too, they also like things dressed up because people like things dressed up. Half of the tech industry is mundane, trivial stuff dressed up, made mystical.
Otherwise, they do actually sufficiently replicate the office environment, and then they’re just criminally depressing. Yes, I’m looking at you, Office Space.
The more they stick to what technology could be like in the future or in an alternate universe, and distance themselves from our real-world systems, the more I can enjoy them. Think the Matrix, Star Trek, Star Wars, etc….
