There are some good examples for decentralization. E-Mail is the most obvious and biggest one. And Git itself is also one, because independent projects can be anywhere. But I genuinely understand why people want a centralized place, because it allows to easily search for things, make stats, have an overview on your stuff, etc. I feel like the only true possibility of an alternative is like such a place, a single project that is consistent everywhere and lets people have their entire work, so that it looks centralized, even if it’s not.
