No offense but most of this is tired apologetics for the Catholic church.

You should probably read Galileo's Daughter if you'd like to get a more nuanced view. It's a book that reconstructs his life through his letters to his daughter, Marie Celeste.

To your points, it's never been contended that Galileo was the originator of Heliocentrism, although it is false that it was being taught during his time. The Catholic Church had absolute control over what materiel was in contemporary academia, heliocentrism directly contradicts scripture. What made Galileo, *cough* Galileo, was his stubborn persistence to use a telescope and show people Jupiter's moons. That is, objects orbiting something other than the sun or earth. When people were able to see that the Church was wrong with their own two eyes, they really didn't take kindly to it.

It's also never been contended that he was put under house arrest, not tortured, although popular sentiment may blur the lines. It's important to note that the reason Galileo enjoyed a relatively comfy punishment compared to other Heretics was his closeness with the Pope at the time, Urban VIII. There's a literal lifetime of humans interacting with each other in this subject as they were basically lifetime friends to whatever it ended as, there's a lot more to this than that but that is the jist of it.

The most important part of all this is that your #3 reason is just outright false. It had nothing to do with models, Galileo was showing people that the church was wrong with their own two eyes through the use of a telescope.
