GitHub has automated Content ID systems for books. ByteByteGo submits the original PDF to GitHub’s DMCA agent. When you upload a PDF, GitHub hashes the file. Even if you rename it to interview_prep_final.pdf, GitHub’s system recognizes the hash and instantly bans the repository.
Furthermore, the community has turned against these repositories. If you open an issue asking for a "free PDF" in a legitimate GitHub repo, you will be banned from that community. The industry standard is shifting toward Open Source learning (like The System Design Primer), not piracy.
If you absolutely cannot pay for the PDF and cannot sign up for Kindle Unlimited, do not resort to sketchy GitHub downloads. Use these free, legal, GitHub-hosted alternatives to prepare for your system design interview: GitHub has automated Content ID systems for books
