Is there any innovation apart from the increase in advertising? Tiktok offers a new suggestion algorithm. Why has something like that not been invented at Youtube? Why does Youtube try to copy Tiktok a bit but does not generalize and does not offer more ways to access videos?

At their position, they could turn Youtube into a platform and let others do the innovation. Instead, they lock it down and double down on their limited user experience.

In 30 years, when something else has been established, Youtube can ask itself why it was not them. But it will take time for a competitor to establish itself and overcome the network effect.
