The lack of capitalism meant that the holodeck program authors had no need to optimize their programs for user retention to show them more ads. So much fewer people suffer from holodeck addiction in Star Trek than are glued to their screens in our world.

Although the funniest thing about the holodeck these days is LLMs have answered a question: can you have realistic non-sentient avatars? Evidently yes, and holodeck authorship is likely a bunch of prompt engineering, with really advanced stuff happening when someone trains a new model or something.

Similarly in Stat Wars with droids: Obi-Wan is right, droids can't think and deserve no real moral consideration because they're just advanced language models in bodies (C3PO insisting on proper protocol because he's a protocol droid is the engineering attempt to keep the LLM on track).
