Touchdown! Greaser!
I doubt I’ll work for a flight school because it won’t be my primary income. But I have zero doubt I will give a lot of free ground school because I love talking aviation and helping myself and others be better at it. Even my worst instructors spent time discussing stuff while off the clock.
You are talking about hobby instruction doing this stuff on Saturday and maybe an evening a week. There noting wrong with being a hobby instructor and if you give an hour or two free, no big deal. Once you realize CFI insurance costs money, you might not be so generous and if you are going to teach in a non-profit club I encourage you to read their insurance policy.
Give an hour free to each of your 8 students at a flight school each week and you soon figure out you are working several weeks for free a year.
