Clearly, I have no dog in this fight. Regardless of any other matter, in which Mark may or may not be less than righteous, returning funds is good. I, as I try to convey in my comment, but try to commend good where I see it can be promoted.
I appreciate that you have more at stake (in multiple meanings of the word), that you seek to represent. I neither have anything I can add to your position, nor feel competent to influence you.
All I am saying is that some folks who have received back their funds will be glad of it, and that it was good to do it.
