This Question is a bit funny because this giant platform you mentioned above didn't start out as a crypto backed platform and even aside that maybe they have no intention to tokenize their business, during the early days of PayPal, Alibaba, Google and the likes i don't think there was anything like blockchain so the platform was created to provide service to those who are interested which totally different now that blockchain is available and upcoming project will rather use it since it provide better service and accuracy in getting the job done, if blockchain was available then who knows maybe one among them would have opted for it.
