Z:gnu-www-ja-google-engineering-talk--47516e-So I found myself in a situati/en

So I found myself in a situation where the only way you could get a modern computer and start to use it was to sign a non-disclosure agreement for some proprietary operating system. Because all the operating systems for modern computers in 1983 were proprietary, and there was no lawful way to get a copy of those operating systems without signing a non-disclosure agreement, which was unethical. So I decided to try to do something about it, to try to change that situation. And the only way I could think of to change it was to write another operating system, and then say as the author "this system is free; you can have it without a non-disclosure agreement and you're welcome to redistribute it to other people. You're welcome to study how it works. You're welcome to change it."
