Winning the copyleft fight

>(To keep this vaguely on-topic: who stands to gain the most from manufacturing such a divide in Linux?)

Microsoft and Apple do. But that's insignificant in comparison to facts-on-the-ground. Suppose there was a Halloween document demonstrating such things to be Microsoft's official strategy -- what changes? Blaming $ELDERS_OF_ZION is a crutch for those who can already walk on their own.

>It would be much more cost-effective to bluntly fix the root problem of those skewed demographics — FOSS has far too many nasty people, some in the public eye often enough that they set the example for “acceptable” behaviour, and some who do it on purpose as job security. Less damage control, more cutting out the damage!

This is just another form of "exclude these people whom I call $OUTGROUP_DU_JOUR". There's no need to do so, and it's a bad idea in any case.

As for holier-than-thous (an amusingly recursive reason for advocating this kind of kickban rules: who's holier than s/h/it who wields that authority?), they and other such cancer will generally fuck off for greener pastures as soon as the current one dries up. This is what establishes the upper bound for their numbers in any given project right now. Notably, this "ignore them" method is the most cost-effective of all by its effectiveness and complete absence of false positives, consequent to forking being always possible -- which in itself drives away those who'd use rules and/or playground bullying to commandeer a community.
