I find a lot of what you just said really confusing and it sounds more like you are believing what you want to believe and are more irritated that you didn't get the stuff you think we should have got. Apocalypse is as much singers baby as X1,X2,DOFP, Apocalypse, Superman returns, jack the giant slayer. Singer even nurtured the creation of FC for few months before Vaughan took over and has taken responsibility for a lot of the decisions made with that movie. The word "rumor" pretty much sums it up Beyond fan speculation there was never a promise that he was ever gonna join his father. And it was in an early script that quicksilver told magneto he was his son but Singer changed it during production.
