It depends, like all things. I am fine with the GPL, but there are ways it hinders open source. A primary example, Linux can benefit from BSD and MIT licensed code, but it doesn't go the other way. FreeBSD can not benefit from GPL code. At least on the BSD side of things, that is why the GPL is disliked. As an example, FreeBSD developers can write a filesystem with the BSD license and Linux can sort yoink that code out of the code tree and use it (supposing nothing special needs to be done with interfaces and such). But the reverse isn't true. If Linux developers write a new FS in the linux kernel and throw a GPL on it, FreeBSD can't utilize that code.
