The only counterpoint is that the departing co-founder really didn't live up to his end of the bargain. Work was low output and quality and this isn't in retrospect. It was like the fellow started crumbling almost from day one & then, the obvious inadequacy of his efforts just sort of piled back on in feedback loop.
So while I feel sorry for the fellow, honestly I do, I also don't really in any way feel that he lived up to any spirit of his commitment to us and his non-performance has hurt us in material ways.
It sort of feels like a choice of either being a jerk or a patsy.
