There are no 'free lunches' in PCa treatment. ADT can have a high physiological (and sometimes mental) cost. Like having your prostate cut out or being irradiated, it's not something most people would choose to do if it wasn't a choice between that and an early death.
HT does improve the statistics, and a patient or healthcare provider who sees that and stops thinking about it at that point will favor hormone therapy whether needed or not.

Do it IF you need it, avoid it if you don't. Look up presentations on managing the side-effects; daily exercise and some meds help.
