If there were "disgusting" photos as you suggested, they've been reported and cleaned up a long time ago.
So, what you are saying is that they can censor, cleanup whatever they want? That doesn't look good. Having a central authority to dictate what is good and what is not, however the mentioned disgusting pictures exist, they just don't show it aka censor selectively.
There is no central authority for Bitcoin.
That's just one front-end. You're free to build your own node and keep everything uncensored as long as you don't care about operating illegally within your legal jurisdiction. Most websites like this one will have a reporting tool for removing illegal material. It's completely impractical not to have one unless you live in one of the few countries that allow any media content.
The blockchain as a whole operates without jurisdiction, but not individual node operators.
If you want to show Ordinal inscriptions, then do it. If you want to prune the witness signatures, then do it. That's the beauty of being able to choose how to run your node.
