I think that this behaviour says much about the bitcoin community, and anyway I take this as an experience on how to deal with it, for my future projects.

Writing here, I just kept the promise I made to Tom, and I really don't gain nor lose anything whether you (and all the others) believe me or not.

I would be sad if Tom will not honor his word with you as he did with me. I am afraid that if you are so aggressive, you only make things worse.

In my opinion it's better to try to understand his situation, try to re-establish communication, and work with him on a plan that allows him to refund everyone.
