The internet has tier 1 network providers that have to obey the law in every country they operate. It is not decentralized at all. Meaning, if I filter your internet at your local provider level you do not have another mean to get to the internet without filtering.

It is possible to block pretty much anything that the country wants to block. It would be impossible to bloack content with a truly decentralized (meaning only peer-to-peer network access) system.

As of today the only thing that comes to close to this is something like Meshstatic. Obviously it is only good for messaging and nothing more at this stage.

I'd recommend you to read on what exactly these tier 1s are doing. Hint: they provide transport. It's technically impossible for them to control L7 for the most of the apps traffic. But that actually doesn't matter in the context of decentralization. Internet networks are decentralized by design. That doesn't mean though there's no control and regulations, but that's irrelevant - something you don't seem to realize.
