“So if I leave my front door unlocked, and a robber comes in a robs me, is it my fault that i was robbed?”
No, but if you pile up your stuff at the road with a “FREE” sign, well...don’t be surprised if its gone tomorrow.
I won’t be surprised, but you correct. Just because a person creates the opportunity for a crime to occur, or in this case an exploit, does not make them responsible for the crime or exploit committed.
The criminal or the exploiter is the responsible party.
