It was also argued by critics that LOCOG's policies made it unviable for smaller businesses to promote themselves using the Games, even in support of athletes, as they would need to evaluate whether their marketing materials violate the restrictions on unauthorized associations. Additionally, the architecture community strongly criticised the marketing restrictions, citing LOCOG's refusal to allow architectural firms to publicise their work on Olympic venues, including preventing the firms from entering national and international award competitions. LOCOG retained rights to all Olympic marks even after the end of the games until they were transferred to the British Olympic Association in 2013.
