I definitely identify with the point about alarm fatigue: as a web developer who is used to spelunking for errors with a single stack trace, seeing 1000 warnings scroll by when compiling a large project (especially someone else's) can be daunting.
That being said I don't see it as a serious issue - if I were really put off by it I would write a utility to customize the output of my compiler to suit my tastes - isn't that what hackers do anyhow?
Seems that the author is annoyed by people in his workplace who enabled "treat warnings as errors" and wrote a rant. You can always disable compiler warnings if you don't like them.
