You really shouldn't blame google, but blame KHTML (who's code base was forked to develop Webkit, and then Blink). KHTML didn't move to support apng until 2010-2011 which was a few years after the webkit fork.
So to get this straight, we should blame the KHTML devs for adding a feature after Google forked it's code? While not blaming Google for never adding the feature?
APNG was still years away when Webkit was forked from KHTML. Webkit was so long ago that Firefox didn't exist, nor did "Mozilla Firebird", and IIRC nor did Phoenix.
