I’m a lot less bothered about rules lawyers than Seth Skorkowsky. In fact it can be useful to have one in the group (who can remember the contents of all those GURPS books in the thick of battle?) and as I’m constitutionally opposed to autocracy I invite the players to cite the rules to challenge my own whims.
I wonder if Seth may have cherry-picked to prove his point, as the example of the player trying to claim a bonus for every use of their spouse’s name does indeed sound irritating – but there is another possible interpretation. Some players take note of the sort of roleplaying flourish that pleases their GM and then exploit that to earn special concessions. So if the original player shouting out his wife’s name was true to character, all well and good; but it could be that the rules-lawyering player was actually making a sarcastic comment on sucking up to the GM’s tastes.
