I didn't see any specific arguments in your post, only the criticism of the church fathers that it doesn't coincide with your professed interpretation of the Bible, so therefore they must be wrong in every instance then too:

So you are a non-JW JW?
The only question is, if all extra-biblical ancient sources were "apostate" (after all, none of them refer to any alleged JW-like primitive Christianity), then where did the ancient JW-like Christians go? Maybe the cat took them away?
The literature of the ancient church is abundant and diverse, but it does not at all support the conspiracy theory propagated by the Watchtower Society, according to which the Christians of the first centuries believed in what they teach according to their current "light": the "use" of the name Jehovah, Jesus as Michael, the Holy Spirit as "active force," two-group salvation, endtime speculations, 1914, true worship disappearing for 1800 years, "house to house" "preaching", only yearly Eucharist without "partaking", etc ec..
It is still not clear where in the New Testament it is prophesied that as soon as the apostles die, the ekklesia can close the curtain, see you in 1,800 years... What about Jesus' promise in Matthew 16:18? Where does the Bible talk about the 1,800-year gap and the necessity of re-establishing the 'ekklesi'a, the second foundation?
The JW denomination did not exist until the end of the 19th century, and its most distinctive doctrines did not develop until at least the 1930s. So if this is the true Christianity, and supposedly the apostles professed the current "lights" of the WTS, then true Christianity did not exist for 1900 years. What is the explanation for this 1,900 year break? Where was your church before Russell, or rather Rutherford?
Everyone who has studied early Christian literature, with the exception of some fluctuations, is basically clear that practically all extra-biblical sources, even before the Constantinian shift, refer to exactly the theology, creeds and Christian self-consciousness that are exclusively reminiscent of Catholic/Orthodox Christianity. Those who opposed this early Christian mainline were smaller, heterodox factions (e.g. Gnostics), in which no Protestant or Protestant background (such as the JWs) today sees its predecessor. In the first three hundred years of Christianity, there was no break of such a nature that the contemporary Christian consciousness would have experienced as a substantial change.
Relevant scriptures: Mt 16:18, Mt 23:2, Jn 14:16, Mt 28:20, Rom 3:3-4, 2 Tim 2:13, 1 Tim 3:15.
JWs and various Protestants usually invoke certain passages, in order to support the alleged apostasy of the Church. They assert that what the Apostle Paul prophesied in his First Epistle to Timothy has been fulfilled, i.e., ‘in later times, SOME will apostatize from the Faith, paying attention to spirits of deception and to demonic teachings etc.’.. But this passage of 1 Timothy 4:1 doesn’t imply that the ENTIRE Church was supposedly going to apostatize. The verse clearly says that “…SOME will apostatize from the Faith….”, not the entire Church
The Bible speaks of those who will apostatize, in other verses also: “…. With faith and an innocent conscience, which SOME – after discarding it – became shipwrecked in their faith” (1 Timothy 1:19); “which SOME, in professing it, strayed from the faith” (1 Timothy 6:21). Furthermore, in Acts 20:28-30, there is no inference that the entire Church is going to apostatize; it only says that “SOME MEN will appear, who will teach the truth falsified”.
The Bible says: “They WENT OUT from us, but they did not really belong to us. For if they had belonged to us, they would have remained with us; but their GOING showed that none of them belonged to us.” (1 John 2:19). It is obvious that this verse proves that those individuals who apostatize from the true faith DO NOT remain in the Church, but move out of it, thus allowing the Church to preserve its dogmatic teaching unadulterated.

The WTS uses the terms "apostate" and "nominal" for other Christians, and there is also a terminological difference that they use the term Christianity only for themselves, while they use the term Christendom for others.
The terms "apostasy", "apostate" are known in Christian tradition and are also used in modern Catholic canon law. They apply to those who specifically left the Christian faith, i.e., converted to a completely different religion, such as Islam, Judaism, Buddhism, etc.
Those who did not reject Christianity itself, but adhere to a belief that is officially condemned, contrary to the declared truth, are not referred to as apostates but as heretics.
So, the word the Watchtower would want to think of when talking about the "great apostasy" would actually be heresy instead of apostasy, but they don't use this, let's consider why:
1. Because due to the "black legend" anti-Catholic propaganda literature, films, etc., about the Middle Ages and the Inquisition, the public associates a negative connotation with this word, and if they were to use the term heresy frequently, they would appear dogmatic, while they actually want to appear flexible, researching, and seeking outwardly.
2. Because they specifically consider only themselves to be Christians, everyone else is not only a branch of Christianity that they consider heretical, but actually qualifies as a different religion, just like Islam. However, this is a very harsh claim, as even the "wicked Inquisition" did not consider Christian movements that did not deny the Christian name but denied many Catholic teachings to be apostates.
They regard Catholics as dogmatic, yet they consider anyone who has been validly baptized in the name of the Father, the Son, and the Holy Spirit to be a Christian, and only those who explicitly renounce the Christian name despite being baptized are considered apostates.
