IANAL, but the GPL contains warranty exceptions, rights of the end user to get access to the sources and other paragraphs, which are targeted to the end user and not (only) to other developers. So, I see that many open source installers use the GPL as a EULA text, but the linked source lacks an explanation of why the GPL could not be seen as such.
