Okay so now I have read through all McKay's comments on that Blabbermouth article (I had to use a different browser to access them) and a few things stand out:
1) He is writing off the cuff - there are so many spelling/typing, grammar and punctuation errors that he would have seen and corrected if he'd read it back it even once. And he rises to the bait surprisingly often considering he must surely have know before he started what kind of people generally comment on Blabbermouth ("Idiot. Go fuck a duck". Really?)
2) He repeats himself a lot, and makes a big deal about things that are not really important (like whether 22AA is really the sequel to CTH - surely it's obvious that regardless of the origins of both songs "Charlotte" is just a character?) And the Seymour Duncan interview with Steve which he refers to (which I think is the same one he referred to just after the last lawsuit, when he first threatened this one) is from May 2017 and it's blatantly obvious from the context that Steve is talking about how they work now - it's not an attempt at a studied explanation of all the different ways they've done things since the year dot. Even the current line-up was of 18 years standing when the interview was done, so I doubt anything from earlier, much less from the chaotic formative years with the revolving door membership, was anywhere near the front of his mind at the time. It doesn't mean he was deliberately lying!
3) Towards the bottom of the page it becomes increasingly apparent that he really hates Steve. He mentions Rod a bit but there's a real personal hatred of Steve that comes through more and more as he goes on. He seems to be trying to convince us that Steve has been acting a part that has fooled just about everyone who has ever dealt with him, that everything we think we know about him is false. And now it's sounding like he doesn't just want to defeat Steve, but to destroy him.
Well, I'm not buying it. Whatever happened during those chaotic early years, what Maiden have become is entirely down to Steve's vision, drive and hard work. Has he made a fortune? Yes, but that's from a lot of hard graft over the last 43 years, most of it more recent even that TNOTB - I think it's unlikely that the songs involved in this lawsuit are significant contributors (the band's ultimate overwhelming success is certainly not built on them). Has he made a few mistakes, miscalculations, errors of judgement over time? Of course. Who hasn't? Maybe he deserves to get his knuckles rapped from time to time. What he does not deserve is complete vilification, as though he no longer deserved any respect or credit for anything. Whatever McKay may be implying I refuse to believe Steve is actually a cruel, heartless bastard who laughs manically to himself about all the people he's cheated and trodden on whenever he's alone. There are just too many people who've met him and claim the opposite (basically, everyone except McKay and Dennis Wilcock ...)
So Steve, in case you ever read this, I love you. You will always have my support and devotion no matter how this, or (God forbid) subsequent lawsuits turn out. Thank you for all your hard work and vision that has given us Iron Maiden, and all that it means to us.
