Is it an essential requirement that in order to design great products or market leading products, management is supposed to work and force others to work during insane hours, especially sunday night?

I am not sure how frequently these things happen. May be ok, when you are near major deadline/shipment date but not on every week. Are there no other ways to avoid them like say, internal wiki/intranet ...etc so that mgmt can search answers on their own?

Many people followed Steve Jobs authoritative style of leadership after reading various accounts...etc. I hope mgmts of other companies won't shift to these methods concluding falsely that such working hours are essential for great products.
