I find the snowflakes equally irritating, but believe there is a huge distinction. This is an individual's blog page, their own corner of the internet, where they can share their opinion and present them in any way they'd like, whereas Apple is designing an Operating System for premium devices used by millions of people that depend on its usability.
They can do whatever they like with their blog, and that's great! But why would I give any weight to the design arguments of someone who designed that thing? It's like if someone comes up to you in a clown costume and starts giving you fashion advice.
