Actually. someone could get money from support (but of course, others can as well). Also, the GPL is also useful when you are developing a product that isn't part of your core business but you wish to gain community support so that all parties involved can gain. It, again, is also useful for the majority of small apps you see on freshmeat. It's also preferred, as shown by companies such as redhat; that once you reach a certain level of commodities of scale with GPL software, then profit with support is also a viable option.

Of course, I also like the BSD license because I can at any time take any BSD licensed code and include it in my proprietary software or solutions. If I was writing software myself, I might choose the BSD license to give to the community -- as well as developing a codebase that I (and others) could turn into commercial products (whether competitively or in completely different products).

Now, If I was developing anything particularly big (time and complexity) from which I want to directly profit from; I may choose something completely or even partially closed. If money didn't matter I might just develop it and put it under the GPL or BSD. If I think I can make money writing something for a company not directly in the software business -- then I do any of the 4.

That's how I see current licensing schemes..
