Article is from 2010.
Note that MISRA is updated with new standards. The version I have is for C99 for example. I’m sure there will or is already one for C11.
You are right.
A few of the guidelines with major criticism appear to be deleted from the subsequent MISRA-2004 guidelines.
Subsequently MISRA-2012 is extended to cover C99 as well.
There doesn’t appear to be one for C11 yet
