In a hypothetical situation where Adam works well & without any bad side effects (which is by no means guaranteed right now), I think it could be really positive.
I definitely don't think women having ONS or other kinds of casual sex should rely on a man saying 'I've got Adam, don't worry about condoms ', (which obviously should be worn for STD protection anyway) but I do think it could work well for women in relationships.
Obviously the side effects of the pill that we've heard about increasingly recently don't affect everyone, but ideally I think it's best for to be able to regulate without pills which disrupt hormones-IUDs are a good solution but can also have side effects. Condoms too but risk of breaking and of course affects sensation. A recent trend promoted cycle tracking, and that CAN work well - only provided it's done perfectly.
Obviously Adam might not be fully effective (likely not) and would probably be used by lots of couples along with something else.
Previous male contraceptive trials I've heard about were for pills, I think an implant is much better given it only takes one mistake for the man to potentially get his partner pregnant, and clearly he wouldn't bear the physical consequences.

So, YANBU- Adam could be good news if it develops effectively
YABU- if it works, it won't be very helpful or even have bad effects
