But this is begging the question. The post assumes that Stallman's good work does outweigh the bad and that the only way to conclude that he is causing problems is if one doesn't believe in the FSF principles at all. But that's just not true. One can absolutely be in support of the most intense FSF principles and still conclude that Stallman is not an appropriate leader. As evidence, consider the actual FSF members who support his ousting. They aren't just corporate stooges who see GPL as a cancer.
And it doesn't seem like that second group has much of an intention to be "charitable" to those in the first group or the sympathizers thereof. That doesn't necessarily mean there's free reign to be as uncharitable as possible, but it does encourage that feeling to be mutual.
