- I thought about these issues a lot when I decided to put my UUCP
- package under the GPL, and I've never seen any argument that was at
- all convincing as to why that was a bad idea. I've seen convincing
- arguments against putting library code under the GPL, but they do not
- apply if you are using shared libraries on a GPL-based operating
- system.
-
- Note also that if you write a piece of free software with the GPL and
- decide later that you made a mistake, you can change your mind and
- relax the conditions. But if you don't copyleft and then realize you
- wish there weren't all those proprietary systems being sold that were
- adapted from your code, there is no way to get the toothpaste back in
- the tube.
-
- Years ago, somebody I'll call X announced he was writing a big free
- software system and called for volunteers to donate code. I
- contributed a program, under a copyleft, while the rest of the system
- was still under development. He said he wanted his system to be
- useful to the largest possible number of people and he convinced me to
- drop the copyleft on the piece I wrote. Then when the big system was
- released, he made the whole thing proprietary to himself. This story
- is not directly relevant to 386bsd, but it's one reason I copyleft all
- nontrivial free software I write these days.
-
- X's system is widely used, by the way---all of you have heard of it.
- I'm glad to see its popularity is finally fading. I'm also glad my
- contribution was extremely minor---I felt like I got away with a
- fairly cheap lesson.
