GPLv2 incompatibility hurts many open source projects, also in the Linux area (Android code is Apache, Linux GPLv2). The Mozilla Public License and the related CDDL are problematic as well: http://en.wikipedia.org/wiki/Common_Development_and_Distribu... (ZFS and DTrace cannot be included in Linux source)
While the FSF portrays them as GPLv2 and earlier compatible, BSD and MIT both require downstream notices and language not required by any version of the GPL, which makes them incompatible with any version before GPLv3, which allows additional terms of the type at issue.
Apache 1.x license is incompatible with GPL.
Apache 2.0 license is a free software license and is compatible with GPLv3+, but not with GPLv2.
