Yeah totally! 

In my case I like the added step, of what I believe is protecting my users. People using tools that involve my software should always have access to the source code and ability to modify it if they see fit, or get it directly from me if they want to. If it's software I or my community developed, people should have access to it. I do understand the economics of that being difficult in some cases though, but I think it's worth it.  

 public domain guarantees that the same as GPL

i prefer it to just be public domain because businesses see it as a utility instead of a rentseeking opportunity that is being "DENIED" 

 Legit question. How does public domain guaruntee that corps who modify my code and ship it to users will ensure access to my source code for users if they want it?
