Sure, innocuous sounding words like "rendition" would never be reappropriated as code for something more sinister, right?
Seems to me that innocuous sounding jargon actually makes Orwellian doublethink much easier to swallow. Like a frog in a slowly heated pot of water, you get exposed to and acclimatize to progressively more problematic uses of power until you simultaneously believe that you are a patriot upholding citizen's rights while routinely violating them.
I'm not really sure why you think this process can't happen in a private company.
