I know WHAT it means to manually untangle, not even purposefully obfuscated, just optimized by the compiler code. Sure, writing code is a passion. Staring at the barely readable decompiled code for years... can be fun if you're autistic enough, but not really good investment of your own free time.
What they're really scared of are open weights models that are smart enough to automate even a small fraction of this task. Because if does, then there is no proprietary software anymore. But on the other side, we may as well lose FOSS too.
