He was just trying to mind his own business before the apparatchiks put a target on him and went after him. Clearly, the adversary was offended that anyone would take the fatima messages seriously. They wanted it done and forgotten, one less obstacle to 'reform'. He just continued on as a man with a mission. Frankly, he still does. He seems to have weathered the storm. I'm glad he did.
Ok, AFAIK, he was preaching "consecration of Russia" as the Fatima message - like a broken record - not, as you state, [again, please, I am not intending to insult or otherwise belittle you] minding his own biz.
His constant preaching on the consecration detracts and detours from the **actual message.
**Fr. Gruner does not preach what the actual message is.
