GoFundMe has been known to cancel campaigns in the past that were politically disfavored by the company or its employees. The biggest example was when they cancelled the campaign to support the Canadian trucker convoy protest against mandated treatment with the experimental COVID vaccines. This was on the basis of trumped up claims of violence and hate symbols by the Canadian govt that do not comport with first-hand experience of people on the ground there. At first the company was brazen enough not to refund the donations and said they would donate them to other charitable causes, but after public outcry they agreed to refund the funds. Didn't help the donors whose bank accounts were subsequently frozen unlawfully by the Canadian govt.

All it would take in this case is for a motivated group of activists to petition the company to remove Colin's campaign on the basis that it promotes transphobia.
