1970年中期（此时Unix还没有商业化），一群黑客和计算机爱好者在硅谷成立了Homebrew计算机俱乐部，致力于免费软件的开发。
1976年初，刚创立不久的Microsoft公司的Bill Gates给Homebrew社区写了一封公开信，阐述了软件产权相关的新概念，那个时候，计算机用户仍然保持着自由分发传递软件的习惯，不怎么考虑软件的所有权。

Bill Gates给计算迷的公开信:
An Open Letter to Hobbyists(1970)

An Open Letter to Hobbyists
To me, the most critical thing in the hobby market right now is the lack of good software courses, books and software itself. Without good software and an owner who understands programming, a hobby computer is wasted. Will quality software be written for the hobby market?
Almost a year ago, Paul Allen and myself, expecting the hobby market to expand, hired Monte David off and developed Altair BASIC. Though the initial work took only two months, the three of us have spent most of the last year documenting, improving and adding features to BASIC. Now we have 4K, 8K, EXTENDED, ROM and DISK BASIC. The value of the computer time we have used exceeds $40,000.
The feedback we have gotten from the hundreds of people who say they are using BASIC has all been positive. Two surprising things are apparent, however, 1) Most of these "users" never bought BASIC (less than 10% of all Altair owners have bought BASIC), and 2) The amount of royalties we have received from sales to hobbyists makes the time spent on Altair BASIC worth less than $2 an hour.
Why is this? As the majority of hobbyists must be aware, most of you steal your software. Hardware must be paid for, but software is something to share. Who cares if the people who worked on it get paid?
Is this fair? One thing you don't do by stealing software is get back at MITS for some problem you may have had. MITS doesn't make money selling software. The royalty paid to us, the manual, the tape and the overhead make it a break-even operation. One thing you do do is prevent good software from being written. Who can afford to do professional work for nothing? What hobbyist can put 3-man years into programming, finding all bugs, documenting his product and distribute for free? The fact is, no one besides us has invested a lot of money in hobby software. We have written 6800 BASIC, and are writing 8080 APL and 6800 APL, but there is very little incentive to make this software available to hobbyists. Most directly, the thing you do is theft.
What about the guys who re-sell Altair BASIC, aren't they making money on hobby software? Yes, but those who have been reported to us may lose in the end. They are the ones who give hobbyists a bad name, and should be kicked out of any club meeting they show up at.
I would appreciate letters from any one who wants to pay up, or has a suggestion or comment. Just write to me at 1180 Alvarado SE, #114, Albuquerque, New Mexico, 87108. Nothing would please me more than being able to hire ten programmers and deluge the hobby market with good software.

公开信思想总结成一句话：不收费就没有好软件！
由此，人们意识到，软件是可以卖钱的。之后，人们的软件版权意识被不断增强。厂商嗅到了商机。大量Unix厂商出现。
