This sounds more like a complaint about human behavior than about the Internet. Why do people eat at chain restaurants and watch blockbuster movies? There's certainly a cost aspect to it, as well as a simple lack of knowledge about what alternatives are available. But generally speaking, people want what other people want; well-run companies simply cater to a pre-existing demand. You can level the same complaints to wearing fast fashion, picking which city to live in, and even choosing a tech stack to implement on. The homogeneity you're dismissing is what most people want in the first place. Decentralization won't change any of that.
