The short answer is no, with one caveat. The court held simply that the Boy Scouts were not a business establishment. This makes sense. Indeed, if the court had ruled that the Boy Scouts must accept people who don't agree with their principles, the Scouts could have appealed to the U. S. Supreme Court on the grounds that their right of association under the First and Fourteenth Amendments of the federal Constitution was violated.
People have the right to join together with like-minded people into clubs.
Clubs can be formed with the express intent to discriminate, such as the Ku Klux Klan. Businesses on the other hand, are open to the public and therefore cannot discriminate. The one caveat of this case is for companies that conduct charity drives that may benefit the Boy Scouts. Just as a business probably would avoid supporting the Ku Klux Klan, so too you may want to avoid giving support to the Boy Scouts or any other organization that discriminates. Case decisions cited here may be reversed.
