We can see during these past few decades how civilization has been crumbling ever since Bugnini et al dared to tinker with the Mass. Michael Hichborn, president of Lepanto Institute, delves into some of the subterfuge of Bugnini and buddies that resulted in the vastly inferior Novus Ordo Mass; please read here. Their end game is the destruction of the Holy Mass.
But this Mass is of Divine origins, so ultimately the forces of evil cannot succeed. As more than a few of us did during the lockdowns, we may have to find this Mass done "off the radar", so to speak. Hundreds of years ago, Catholic Ireland faced the same dilemma. They took to the hills and offered Mass there. We may have to do the same as did our forefathers long ago. Our Lady of Fatima promised that in the end, her Immaculate Heart, and Our Lord, would triumph. Meanwhile, with Rosary in hand and hearing the Latin Mass wherever we can, we must stand firm.
