i completely agree with you. i think the people who advocate for auto-formatters must not be very skilled at using their text-editors and/or don't put enough attention on readability/understandability. i'm happy with linters and command line tools to auto-format when you explicitly call for it, like `eslint --fix`; i'm just not on board with the formatter running on git hooks or in whatever automated workflow.
almost every rule has an exception where understandability could be improved by violating the rule, ex. line length. code format is huge for understandability/readability, which makes it worth paying attention to while you're writing.
in my experience the loudest advocates for code formatters are the ones who write really complicated code; which makes sense that they just hammer on code until it works without being able to reduce and simplify their logic and naming.
