I didn't only disagree with some patches, I disagree with most of the feature decisions, management and bugfix handling. And esp. with their negative track record. perl5 deserves a properly managed project and the perl6 features, so I did it. At an important time, with :const, types and signatures upcoming. And perl5 should not be used in public services due to its lack of security (I am warning against it since 5.16), not talking about the feature mishandling.
See the perl11 blog.
Some numbers: In the last 2 years, p5p produced 12005 commits (2 releases), whilst I produced 6291 commits. That's >30%. The 2nd most prolific author did 3104 (unicode), the third 1689. And I squash commits into features and bugfixes and don't spread it out over 3-5 postfixes, because cperl works in branches, not posting directly to master. Of those 6291 commits you have nothing in perl5, but they continue to play stupid and take nothing. Features wise and security fixes it's more like 1000%, not 30%.
