I don't think that it is Namecheap's duty to donate any portion of their profits to the EFF, CC, Deb, etc... If I want to support those initiatives, I will make the donation myself (and get the tax refund).

Namecheap does quite a bit more than GoDaddy in terms of protecting you.

To GoDaddy, you are some cow that needs milking. (re: fines for various "infractions" that GoDaddy writes up themselves).

To Namecheap, you are a valued and respected customer. This means requiring proof to back up accusations.
