Earlier quoted context omitted.
I really do not like that you continue to call these students ignorant and arrogant.
Are they not? The rules clearly state "no Github", and when confronted with that fact their response is "it's stupid" and to go off on tangents about Github this and Github that. That's being ignorant of the rules, and being arrogant when you are told to abide them next time.
I actually learned the opposite of what you're preaching in school. I struggled to shorten a report to meet requirements. A friend of mine was 10 pages over the limit and went on to win a laptop with his report.
Some rules are more akin to guidelines, turns out. It's not unreasonable to interpret this instances' rule as "no templates" rather than "no GitHub".
