The rules nazi crowd is correct in this instance, but still incredibly annoying and petty in the grand scheme. Looking at you
JC17393.
There are two general kinds of rules. There are rules of play and etiquette rules. One dictates the parameters for success within the activity. The other penalizes unwanted conduct. Rule nazis treat both types of rules exactly the same. To them wearing black at Wimbledon is the same level offense as faulting on a serve. The rest of us can make a clear distinction between these two things and generally allow violations of etiquette rules until they become vexing. When a rule nazi attempts to enforce slight violations of etiquette rules the rest of us correctly see this as petty and trying to win without any display of skill.
But, wearing black is not overlooked. In fact, the penalty of disqualification can be enforced for dress code violations at Wimbledon, service faults do not carry such a penalty.
In this exact instance the rule was a rule of play. The competitors received a very small but still measurable boost to their chances by not having to put away their tap ins. The rule should have been observed. But now let's move on to the level of outrage.
Reasonable people want the game of skill to be decided on skill and skill alone. Rule nazis couldn't care less. They want people to lose if they break the rules, even if they displayed demonstrably more skill in their game. I think most reasonable people disagree with this. Nikko and co. broke the rules, they should not have, but in the end the results were not significantly impacted. The level of outrage should be directly proportional to the net impact of the rule violation.
So rules should be set by your definition of skilled, and the level of potential impact of rules should be subjective based on your perception of their impact to the outcome?
In dealing with many people in all walks of life, I often find that rules nazis are usually very entitled individuals. They do not like the idea of skill trumping "the rules" as in life their main advantage is not skill but birthright to a higher social status. On the contrary people with a lax viewpoint towards rules have usually succeeded based on skill and aptitude, and are maybe a bit arrogant in feeling above the law.
