I agree with you 100%
This is my take on it. It would be normal to think that anyone with a heart and a moral compass would be pretty appalled of the exploitation of E2 and his siblings let alone Anna and Jonathan's family members but I have to say their silence on this is deafening and their zero action to make it known they are and or step in, leaves me asking, how can they just sit idly by and watch all this play out and like you said no one is protecting him.
Whether or not A & J's families have spoken to them in private, behind closed doors, who knows, but if they have it has gone on deaf ears and knowing the type of person Jonathan is he would of gone on the counterattack, but if A & J were my relative I wouldn't be able to just keep sitting by and watch the abuse to their kids keep going on and on without knowing I could have done more, but that's just me and how my mind works.
One thing I have noticed which grates on me is if you look at some of A & J’s IG posts on their grid with the kids, whether its an AD using their kids as props or A& J addressing the "the whole eduardo situation" (their words) they did a live on this, you will find on J's IG grid about E2 wearing dresses, consent and justifying why, coming from their disturbing mentality and skewed perspective, you will find and see Anna's mum, Margaret in the comments section of these posts and many other posts with her emoji response's, giving her blessing so to speak, reacting to these posts with love hearts, clapping hands, laughing face, smiley face with tears of joy, smiley face with love hearts, thumbs up as well as many other similar ones, too many to list here. This signifies to me that she mustn't have an issue with it and must be on board in full support of her grandchildren being exploited and used for financial gain by her daughter & son in law.
I guess what’s so disheartening & disappointing to me is to see Anna's mum and others are looking on without so much as a protest and not making some attempt to intervene and be a voice for those poor kids.
