But wouldn't opening up such an important (from what I understand) part of a computer to everyone mean that malicious actors have a much easier time doing malicious stuff? I understand (and support) that enthusiasts will have many more options when presented with the actual code to a program. Nonetheless, I can't help but feel like if you give everyone a tour and show them how their super secure door locks work, including how to break them open, then those that want to break in, will be very happy about it and the security system quickly becomes useless.

Please feel free to correct me on wherever I am wrong. I tried reading through the article, but I only understand a fraction of it.
