Criticism
The PHP License is an open source license according to the Open Source Initiative, and a non-copyleft free software license according to the Free Software Foundation.[3][2] The license is GPL-incompatible due to restrictions on the usage of the term PHP.[2]
Debian maintainers have had a long-standing discussion (since at least 2005) about the validity of the PHP license.[5] Expressed concerns include that the license "contains statements about the software it covers that are specific to distributing PHP itself", which, for other software than PHP itself therefore would be "false statements".
