I don’t think that essay does what you want. It seems to be about “you can’t always capture the meaning of something by writing down defining a simple precise definition”, while the complaint is that you’re not using the word according to its widely agreed-upon meaning. If you don’t want to keep explaining what you specifically mean by “breakthrough” in your title each time, you could simply change to a more descriptive word.

A quick google search should show you that the way I am using the word “breakthrough” is in accordance with the common parlance.
