What?‽ You guys are goofy, there's no fake littlefinger plot, did you watch the last season? They can't even handle the subtlety of the idea that having characters that both know something acting like they don't know it just to fool the audience comes across as bullshit. Why were arya and sansa acting for so long like they believed littlefinger when they were the only ones there? The only possible reason was to fool the audience. But how fucking stupid do they think we are? It's like when they killed Jon Snow and then were like "No he's dead for realz, no way he's getting resurrected by the magic lady from the resurrection religion who just so happens to be in the same place.
That's the issue they're having after they got past the books. The character's actions are transparently treating the audience as a character. They do things for the only possible reason of misleading the audience. I mean, you don't want the audience to be able to see everything coming, but you really need to maintain the illusion that the characters are doing things for reasons that make some kind of sense.
