I think his game plan is clear.

He wants to make a legal claim to the fact he is "Satoshi", and then he will have the court issue an order that the BTC (and BCH and BSV devs) make a change to the code that allows him to access the keys to the "Satoshi coins" on his list.

His funder has made 10 figures using the courts for this sort of shenanigans for years.

As much as I think he is a horrible person, this drama is somewhat interesting.  One interesting point is, if my some stroke of luck he actually can get the "order" to have BTC code changed to grant him access we will see yet another fork.  Obviously the real bitcoin devs will not changer the code.  But someone will, and that fork will be launched, and declared the "true bitcoin" or even the "true BTC".

This is tiresome.  But it is also a reality, and one of the sorts of attacks on Bitcoin that I do not think (the actual) Satoshi foresaw.  Nor did the others 10 years ago who had somewhat better vision than him like Finney.

I hear many people calling for the code to be "ossified".  That even the hard fought improvements like Taproot/Schnorr are not worth the social risk.  But I think they are stopping one level too short of where the REAL ossification has to happen and HAS BEEN happening.

That is the ossification of consensus.  We can have as many copies of Bitcoin created as there are places to store the blockchain.  And the argument by many no-coiners that there are "endless bitcoins" because there are "endless forks, and alts" is easily brushed aside by the true believers, but in reality it is important, and necessary for us to go through this process during the birth of a new monetary network.  The tradeoff with this network being FOSS is it can be forked as many times as people want to fork it.  And that is where one of the most viable realms of attacks are.  Wright and Ayre have been gathering as many followers and believers as possible in an alternate vision for Bitcoin to the end that they can subvert it, take it over, and be the central authority of it.

This seems very futile to me, in light of the fact that the network has CLEARLY shown where consensus lies for the last 4 years as well as the fact that relative new converts (and ones in power like President Bukele) have also correctly evaluated the landscape and seen that Bitcoin, with all it's choices and tradeoffs is ONE THING, and there is no need to listen to the various siren songs of imitators and subverters.

But it is still going to happen. And things like default judgements in the courts etc will happen, and that wedge will be driven as far as possible before trying to do the eventual "flip".

Of course this is futile, and annoying.  I wish i had some clarity on the way this continues to unfold, but I see to many competing possibilities.  But most future universes end in failure for our friends the frauds.  It's just that the real thing ends up having to walk through this mud on the way to rock solid establishment.
