Because quality projects like symphony Symfony 2 does not fit into his works view of php.
If Symfony is so amazing, why does nobody use it? I mean nobody in the almost literal sense. Stack Overflow serves as a rough barometer of popularity and either Symfony users have no questions, use another support platform, or they don't make up a significant population. The #1 problem with the PHP community is it's complete anarchy and filled with people that should not be developing web apps, or at least should not…
I am specifically talking about Symfony2, by the way.
A great number of frameworks and CMSs are using Symfony2 components. Two popular ones are the http-kernel and http-foundation components.
Drupal is integrating several Symfony2 components.
Composer, the PHP package manager that has taken the community by storm, is using Symfony components.
eZ publish is integrating several Symfony2 components.
Joomla! adopted YAML, using a Symfony2 component.
Stating that Symfony2 is not widely used simply tells me you're not keeping up with the PHP community - which would be fine if you're not a PHP developer, but makes your statement not trustworthy.
edit: PHPUnit, the defacto standard PHP unit testing framework, also uses Symfony2's YAML component.
I can go on.
