How does every single blockchain project call themselves decentralized but all of them have a centralized development team?

Is everyone too scared to talk about how the entire blockchain world relies on centralized development teams? I’m wondering how come no one is talking about this issue?

What people are calling "decentralized" isn't decentralized whatsoever. You have a group of people that start a foundation or a company, in some obscure location around the world, then they release what they call a "decentralized" product.

You may say, what about Bitcoin, there's no company. Well, is that the difference between decentralized and non-decentralized, having an officially registered company?

Imagine a team, a development team of 10 or more developers, is in control of billions and billions of dollars, and during this time, all other new projects seem to do the same. You can't have true decentralization without decentralizing the development process. Look at all the projects that claimed to be centralized recently but locked users funds like Celsius for example.

I think this is what’s missing in today’s blockchains, what does everyone think about this?
