The other explanation comes from control and subversion. The modern Roman Catholic Church basically supports, or is gradually on its way to supporting, everything that Western globalist oligarchs support (covidism, depop, climate change agenda, lgbt, feminism, etc). This is not a coincidence. The oligarchs, through proxies like intelligence agencies, have subverted the Vatican to use it for their own purposes. This is also why the notion of an infallible office at the head of the Church is patently absurd. The CIA, for example, wanted to use the Vatican (with its over 1 billion followers) as a tool to help the US fight the Cold War. It's no surprise, then, that in the 1960s onwards the Vatican started to adopt positions that were previously condemned in the RCC as the heresy of Americanism (ecumenism, preference for democracy over monarchy, separation of church and state, etc).
If anyone doesn't believe this, just ask yourself 2 questions:
1. If I was a trillionaire in control of entire countries, would I be interested in using the influence of a large powerful organization like the RCC (with over a billion followers) for my own purposes?
2. If I was a trillionaire in control of entire countries, could I find a way to infiltrate the Roman Catholic hierarchy if I wanted to?
If you answered yes to both of these questions, then it's pretty obvious what the reality is.
Orthodoxy has similar problems, but thankfully it's much more decentralized, and so infiltrating the Orthodox Church would require infiltrating thousands of dioceses around the world instead of just focusing on one diocese that controls them all (Rome). Moreover, the Orthodox Church keeps the ancient tradition of appointing bishops locally (instead of the pope single handedly choosing every bishop in the world since the 1100s in the RCC), through local councils, and drawing these bishops from the ranks of the monks (men who've already been living harsh/ascetic lives in some monastery where there's a lot of accountability for many years before being appointed a bishop). Furthermore, parts of the Orthodox Church keep other parts accountable, and there's no infallible head who can't be challenged. So, if the Soviets infiltrated the Russian Orthodox hierarchy (which they did), then they can't just start changing things, because everyone will see that there are still entire Orthodox countries outside of their control who didn't change, and there are respected/beloved leaders like the holy elders on Mount Athos, who show and teach what authentic Orthodoxy is.
Any RC priest could be pope or bishop one day. If a man is pre-selected by some oligarch institution to infiltrate the RCC, then he doesn't necessarily have to sacrifice much to become a RC priest if he's homosexual. He works only one day a week if he wants, lives comfortably off of his salary and flock, and usually lives alone so can continue pursuing a homosexual lifestyle in secret if he wishes. If he was forced to be in a monastery for 10+ years he probably wouldn't be able to handle it, everyone in the monastery would see that he's not trying to change his life, and so finding people who are willing and able to infiltrate the hierarchy will then be much more difficult.
