Not all hacking is the same.
Clearly there are criminal hackers looking to get financial information, social security and credit cards numbers for the purpose of stealing.
There are also personal hackers who may not trust their spouse or significant other and desire to snoop around to see if they're cheating. Others are "stalkers" targeting (email & social media)
There are government agency hackers looking to solve or prevent crimes as well as spy on other nations.
Last but not least there are hackers whose primary goal is to shut down the world of many if only for a few hours or minutes. These people plant viruses, malware, and Trojan horse email links just to see how far it spreads. Releasing nude photos of celebrities.
It's just their way of having "fun".
The bigger the entity is that's shut down/exposed the better.
