Moxie Marlinspike's My first impressions of web3 is also a very relevant thing to share.
As a sampler of the points made, web3 is already re-centralizing around gatekeepers because the average person doesn't want to run their own server (or, in the blockchain case, host their own full copy of the blockchain) and, if the supermajority of users can't see you because the gatekeepers block you, then it doesn't really matter that you're technically still up.
The takeaway on that particular point is that pushing for more and easier data portability is probably the best route in the face of how real-world users behave. (eg. anything stored in a git repository, including GitHub project wiki contents, is a great example of that. You've got your data locally with a simple git clone and you can upload it to a competing service with a simple git push.)
