Sorry, no!
Iesous is phonetically Yay-soos, which has no relation to Yeshua nor Yehoshua.
If you were paying attention, you are already seeing that Yshu and Yay-soo are exactly the same. The s is usually added for Greek pronunciations
The Greek text uses the curse, not his name.
You are a Johnny come lately on the issue of the name of our savior. As an English speaker, I doubt you know Greek better than the ECF, the “Early Church Fathers” who lived and wrote around 1800 years ago.
They knew Greek well, they lived much closer to the events of the New Testament than you - and not a one of them saw the name Iesous as a curse.
They wrote “Iesous” in hundreds of places. You hold to a modern theory far removed from the truth.
Seriously, where do you get this stuff? What brand of Christianity are you signing off on?
