Depends on country as well. There was recently a case in Finland where a couple of people found issue in certain locks made by Abloy. They were offering to sell the details to Abloy and suggested that they could alternatively publish them in Youtube. They were found guilty for extreme blackmail (I'm not sure if extreme is the proper term in English, essentially just more extreme form due to e.g. demanding a lot of money). They are planning to appeal it so there is chance it will get overturned.
