It's always difficult to know exactly what people do with the software once it's out there "in the wild". Many of my projects are just curiosities with no other contributors, but a few have had many improvements submitted - some of them quite substantial. My guess is that if the GPL projects used BSD this would not make a big difference, but it might limit the ability to combine my own code with other GPL'd algorithms. The predominance of GPL as a FOSS license means that adopting it basically maximises the potential usefulness of the code, and since IANAL I'm not really qualified to judge compatibility between different sorts of licenses.
