In your own personal opinion it's an "expoit". But if it's functioning within the consensus rules, then technically it isn't. But this is is what I'll tell you, and I believe we could be of the same opinion,
- Ordinals by itself is not technically an "exploit", BUT it can be used as an attack vector to impede and interrupt financial transactions in the Bitcoin blockchain.
We've already established this a long time ago. I believe it was in spring!
Everyone who disagreed with me calling it "Attack" agreed that Ordinals is using an exploit in the protocol to spam the chain ergo it is an exploit itself.
Keep in mind that saying "it is functioning within the consensus rules" doesn't change the fact that it is an exploit. Consensus rules can be broken and in need of a fix too. Sometimes it is a very severe case like the value overflow incident[1], sometimes it is less severe like the countless number of cases being patched by standard rules.
