I also remember my time at Yahoo! where he repeatedly expressed his disdain of frameworks on the internal mailing lists. Yahoo! heavily relied on PHP but did not have a web development framework. Rasmus's intent for each developer was to start from scratch every single time. Result was a much steeper learning curve, significantly lower efficiency, and plethora of security issues that a framework would typically mitigate behind the scenes. By the time Yahoo! adopted Symfony (~2009), it was way too late in my opinion.
