Even if they were, would that matter?
Civil Rights Act of 1964:
> All persons shall be entitled to the full and equal enjoyment of the goods, services, facilities, and privileges, advantages, and accommodations of any place of public accommodation, as defined in this section, without discrimination or segregation on the ground of race, color, religion, or national origin.
GoDaddy is not a restaurant, hotel, or any other "public accommodation" business as defined by law.
AFAIK, GoDaddy could also discriminate against Jewish customers (which is a protected class) all day long and not be in violation of federal U.S. law
