I for the life of me can't understand removing people who point out such critical issues from your community. Is it greed? Ignorance? Complete unawareness of the Streisand effect?
I presume that this was an attempt to prevent the complainer from complaining in their public forum where it would be read by other users of their product.
Why check and see if they have a point, when it's easier to assume they're a crank and extortionist and ban them? Gets you the nice feeling of making it all go away immediately.
