They weren't obligated to continue to collect money on their behalf, but once they started collecting that money, they are obligated to handle it responsibly. They do not get to decide to withhold money unilaterally and give it to other charities (as GoFundMe has stated they intend to do).
A telephone company can't decide to give me a phone number then tell me who I can or cannot call. My ISP cannot tell me which websites I can or cannot access (without a court order). If GoFundMe allowed the convoy to open a charity drive, they cannot unilaterally close it and confiscate the money.
