I feel the author has overstated the challenges of decompiling back to source as an IP protection mechanism. Certainly you won’t get as clean of code, but it isn’t going to hide IP considering everyone has access to both open-source and commercial decompilers like uxmal/reko: Reko is a binary decompiler. (github.com) and Hex-Rays Decompiler – Hex Rays (hex-rays.com), just to name two I found with a quick search.
