I usually drink the DHH koolaide when it comes to Rails decisions, but I'm surprised by this decision exactly because of his arguments against being forced to write specific styles. I enjoyed default RuboCop when I was first learning Ruby to gain idiomatic knowledge, and strongly disliked after I took off my training wheels. I don't even like using `standard-rb`, which is a much more tolerant configuration of Rubocop. There are often reasons to disregard certain style rules, and I don't want to ask for permission in `# magic disable comments`.

I strongly agree with all of his descriptions of formatting and linting. I also strongly agree with him putting his personal style into Rubocop for the Rails codebase itself, and for project maintainers to be in control of what, if any, style they wish to enforce. But to omakase his style-guide into the consuming projects is surprising and against the very arguments against conforming to style-guides he presents in the first half of the post.
