one small note: "all profits to charity" doesnt mean much. it means that the CEOs, presidents, and execs can simply pay themselves whatever wage they want and whats left as "profits" is donated.
that aside, it indeed looks like he gave plenty away to charitable organizations. sorry to have another negative view on this, but with many of those charities, a lot of the money that is donated goes to the administrative fees and paying their own execs (for example, the president of the red cross gets 600,000 USD per year as a salary*). some of the donations finally trickle down to the actual needy, but not enough, IMO. thats why i like to donate directly to the people and leave the organizations out.
