Hmmm. One of these things does not belong.

Interesting, fine. That’s very different than important or relevant or necessary.
Bitcoin acts in mysterious ways. Bitcoiners need to be open to the fact they do not know best IMO.
Ordinals is not a protocol. It is a scheme. The usefulness of inscriptions is debateable but not because of Ordinals, because of Bitcoin. Bitcoin provides the immutable chronological storage of transaction data. Ordinaks just sit on the sideline playing a game that purports to track that data. Big difference from being an open protocol akin to Bitcoin, Lightning, or even Nostr.
I don’t think I can disagree with this, other than to say there could be subjectivity in the definition of a protocol.
I almost (and may still) include Taro into the category with Ordinals, just to highlight the ability to store and transmit content in an immutable and censorship resistant way.

Agree! One of these is an attack vector that helps to slow the transition between the slavery based fiat world to the freedom based bitcoin world.
