Yes, in a strictly semantic sense, it is a limitation. However, in general such access would be not only a bad idea due to the loss of abstraction and additional work to implement (duplicate) access controls, it would also not be very useful for users over the multiple possibilities for access that already exist.

And all this is really a red herring, both in relation to the unspecified use of blockchain and in relation to resistance to state censorship.

No, it's not a red herring. The point is that Wikipedia could use a database that didn't rely on a limited number of access endpoints, which would make it harder to censor. And you don't need duplicate access controls if the database implemented them fully.

This is not restricted to the blockchain, of course. Something like e.g. SSB fits the bill.

Since not all information in the database is public, yes, you'd need to duplicate the work. You'd also need to put a lot of work into securing the now open service against attack and denial of service.

It would still be just as easy to censor. If a censor goes beyond simple DNS manipulation and drops packages to specific IPs, he can just as easily add the few hundred IPs of database servers to that list as he can add the few hundred IPs of the frontend web servers.

Now, your example of SSB shows very well why this is a red herring. Even if Mediawiki put in the huge work to use SSB as a storage backend, nothing would change at all regarding censorship. What you really want is, I assume, a federated version of Wikimedia's architecture.

Feel free to develop such a system but I don't think anything but a complete rewrite of Mediawiki would allow for that, and even then, I doubt it would be much more censorship resistant, unless you also take on such features like using TOR hidden services or invite-only networks, which are both perfectly possible right now (and are in fact available right now).

And as I said, there is a multitude of options to access the data right now. For example, to build mirrors of Wikipedia for citizens of countries where Wikipedia is blocked. However, it's not necessarily trivial and it doesn't get easier simply by sprinkling some cryptography over the storage layer of all places.
