content: not exactly , a lot by percentage is as you say, but biggest is patents folder. Patents whitepaper part is 27 GB. Actual text file source code of each os would never be over 300 megabytes each, so yes, there appears to be some media added to it possibly with steganography hidden data reprocessed into the media using a transcoding mp4 steganography tool to embed other source code within.

technique allowing list of torrent participants to claim they only up and downloaded the media files, not the source. Or if the mp4 files have hidden data in them, as mentioned. discussed for over 11 years : DOI: 10.1504/IJAMC.2009.028712 : MP4Stego: steganography in MPEG-4 videos (PDF) https://files.catbox.moe/9b7m4e.pdf That paper is weak sauce lame in one way, it uses blatant "look at this hidden stuff" method of adding a noncritical encrypted stream (MPEGlet stream). The type of steganography used in MP4s the last 4 years for nation states and high IQ actors would stay within the audio and visual data realm, and using chaos noise, or Generative Adversarial Network reality alterations, not lazily add a ham-fisted extra data stream like in that older paper does, but that paper's DOI can be used to locate better more modern papers that do real and covert steganography.. usenet has two of these operating systems this week, as mentioned in this thread.
