Having worked in tech for two and a half decades, and in places that were this direct - no thanks. There’s a fine line between being clear and direct, and being toxic - what Torvalds did here was toxic, and in many workplaces of today would be classed as bullying. Being subjected to this ‘directness’ for any given amount of time will do a number on most people’s personality and self-esteem. People don’t improve themselves if all you do is shit on them.
