Unless whatever service accessed the tweet/image/text/whatever made a local copy and is displaying that once the "blockchain service" no longer allows access.

An NFT doesn't confer access control. Its a certificate of ownership, the asset itself is infinitely reproducible.

NFTs represent something else completely, I'm talking of other use cases that are enabled by the same underlying tech - with the disclaimer I mentioned above of pending issues to be resolved, particulaly gas fees

if you are not aware of how something like what I described could work maybe have a read around on some simple smart contracts where there is hidden state (like guess the answer or contracts that implement role access/control for certain features)

Regardless of what relationship a piece of data has to some blockchain technology: As soon as it is publicly accessible, even once, it's scarcity can no longer be guaranteed, because by their very nature, digital assets are infinitely reproducible.
