Maybe Meghan should be suing her friends for breaching her privacy
Isn't this what Wayne Rooney's wife is doing re the other footballer's wife who she 'entrapped' via fake IG posts? The difference, of course, is that a footballer's wife has money (and arguably Wayne Rooney's wife has more money than MM) and a reputation that Rooney's wife might have an acute interest in damaging. I'm guessing none of the 5 who spoke to People magazine have as much money. Why waste time and money suing them? Easier just to cut them out of your life. Also, those 5 people speaking to a 'journalist' at People magazine about the letter wouldn't have done any harm. The harm occurred when the letter was published for all and sundry to read. You'd go after the publisher (DM's owners) for disseminating the information and because they have deep pockets. (Disclaimer: I don't know the ins and outs and the particulars of claim, so this may not be actually be why! Just a general comment).
Also, Harry has history with the British tabloids. It's personal for him, which makes it all the more ill-advised.

I'm wondering why she didn't go for defamation actually, if she feels that strongly about the lies and volume of negative press
I don't think the reproduction of the letter "defamed" MM. I think the contention is that it breached her privacy. It was her Dad who handed the letter over two the DM. He and the DM breached her privacy. Fancy raking your dad over the coals in court. That's a completely different level of harm that you wish on someone, compared to privately saying your piece and cutting them out of your life.
what have all these new claims and submissions, such as how her wedding generated £1bn of revenue, she wasn't protected by the institution etc, got to do with a breach of copyright case
I think this is why you don't go to court about these things. There's so much back and forth, between allegations, defence, rebuttal etc. It's possible/probable that in its defence the DM's owners contended something (eg MM was a person in the public interest, because xxx million pounds was spent on her wedding which was televised world wide blah blah blah), to which MM's team might reply "well actually, it was yyy million pounds, and anyway it was a largely privately funded event because Charles footed the bill for the dress/ flowers /cake /alcohol/scented candles etc, the taxpayer only paid for security for their own protection". I think. The process of discovery, claim, counter-claim is what you want to avoid, and you certainly don't want to put yourself in the spotlight by actually appearing in court (virtually or in person). It's completely ludicrous, totally hot-headed.
