Which is why the Church has become so unable to deal with the other moral declines. The plank in thy own eye.
There was a period of time after Vatican 2 when annulments were far too easy to obtain. I believe that has been tightened up a good bit over the past several years.
As for the article, it is way over the top. Many annulments are obtained for quite valid reasons. One example would be when a Catholic marries outside of the Church and later secures a civil divorce. As that Catholic’s marriage was not considered valid in the eyes of the Church, for whatever reason, the Church requires that an annulment be secured in order for that person to later marry another person but this time in a Catholic ceremony. Generally, one is automatically issued within a month or two.
Another example is when a Catholic marriage later produces no children because one of the parties refuses to have any children. As the primary purpose of marriage is procreation, the Church can consider the marriage to be invalid.
