It’s probably a pacing thing. Having a section of the film where the protagonist has to sit down and learn about threat models, flash a Tails image to a USB stick and fiddle around with PGP keys before they can communicate securely would probably ruin the vibe.
If I get time to find it I’ll post it but there was a famous study where researchers in the UK looked at a smart thermostat and figured out how many privacy disclaimers you would need to agree to to use it lawfully. It was in the hundreds. There was also those photos of kids on the toilet that were taken by an Amazon robotic vacuum cleaner that got leaked. And police getting called out to a murder in the US that was recorded by Alexa.
