What a terrible way to take constructive feedback.

Writing not one but two blog posts takes time and effort, moreso when it includes investigation and examples... the posts are not just low effort "this is crap" rants (and they even blame themselves, even though it's clear from the posts that there are documentation/discoverability issues).

What if the poster doesn't feel knowledgeable enough to contribute code? (as shown by his first post title, "I'm too dumb for...")

If that's not collaborating I don't know what it is...
