At the end of the day lying in court is quite the faux par to make. If the article is to be believed William would have had two choices, a) approve the release of
some of the texts or b) turn a blind eye to lying in court. Given his position (and future position) I don't think (b) is an option.
If he were to go for option (b) Harry has his book coming out next year and could quite easily drop PW in it (or for that matter anyone in the circle could blab if the price was right) that PW was in cahoots over lying in court and was complicit in covering it up.
William is playing the longer game which is something that is totally at odds with his brother. Just my little old opinion.
Not only has the case gone on already and MM had won, this was digging back and involving himself in something that had nothing to do with the case nor Knauf or William.
William does not need to do anything, he was not subpoenaed, neither was JK.
No one would blame William for saying, the rules of the company (palace) are that the documents are private. Just the same as when the police try to search your house and you say, where is your warrant. So all he has to do is wait for the subpoena.
Here they chased down Meghan when they had nothing at all to do with the case and the information has nothing to do with the case.
What will happen now is that the information will be once again discounted as it was last time, and MM will win again. So this long game may well blow up in his face. As you say, then surely Harry, if he was going to hold back, cannot if his brother is going after them like this.
Also as you say, some of the messages. JK left out, some messages to make sure it's damaging to MM.
