ELI5, during winters and colder seasons you’re told not to use the handbrake of it possibly freezing. Why wouldn’t a gear in a gearbox freeze as well?

What? Don't use the handbrake in winter? 

I have driven manual in Canada for 20 years and never had an issue. 

If nothing else, the engine can EASILY overpower a parking brake and that will heat it up real quick.

This advice is probably 50 years old.
