People are moaning because they feel tricked into creating account and giving their name and email. I don’t know if that info will be used for marketing purposes, but if that’s the case then it’s fucked up.
About donation… Cancer research already receives millions upon millions of donations. It’s not a problem of money. Giving a few k would be like drop in a ocean.
But you can make real difference with some charities like fight for the forgotten or water4. People are dying because they don’t have the absolute basic – clean water.
