My initial thoughts are that the writer of this article is jumping to a few conclusions about the SSPX, and may not be aware of a number of reasons why people choose SSPX.
From my perspective, the Novus Ordo is going down a path that leads to a One World Government. You even hear of some of the higher ups in Rome promoting the concept of a One World Government. To me this is a major concern, and a red flag. Its not only what some of these leaders have said, but what the modern Catechism is teaching as well. You could almost take it as they are not in full Communion with God since they are saying these things. But I am going to try to not go that far with it.
Not to mention, we have the prophecies of the Saints over the last 150 years or so that warned about a council (Vatican II) that would happen in the 20th century. This council, according to the prophecies, would eventually not be good and cause turmoil in the Church. There is even the prophecy of St. Nilus (5th century) that warned about how the traditions of the Church would change, in the 20th century, during the advent of the Antichrist. I know I have spammed that prophecy on this site a few times, but I think it is important.
These prophecies are certainly not something one should over look.
