When you're talking about tokens, businesses can tokenize their stocks, marketing materials, reward points, governance, and use tokens as their own currency to retain customers. There are so many benefits that the question should be why aren't all companies creating their own tokens yet?
Because some companies may not want it. Coming back as you said, it has to do with how functional those tokens would be if they were to create them. This will make the company healthier in public judgment.
Imo, if a company tokwnizes the platform/service at the beginning, it's like forcing people to make it valuable, while the company itself was just established and still in the early stages of development, meaning that it didn't yet have any value at that time.
