So, you know how sometimes people want to change things about the world that they think are not fair or that hurt others? Well, some of these people are called "hacktivists".
"Hacktivism" is when people use computer skills to spread a message or to fight against something bad. It's like using the power of the internet to make a statement, like shouting from a rooftop.
Now, some people might think that hacking is bad, but hacktivists use their skills for good reasons. They might hack into a company's computer to show that the company is doing something wrong (like hurting the environment) and make people aware of it.
Hacktivists also use their skills to protect other people's privacy and safety online. They might help people in countries where internet access is restricted, so they can communicate and share ideas with the world without getting into trouble.
So, hacktivismo is like a group of hacktivists who work together to make the world a better place through their computer skills. They are like superheroes, but instead of capes and masks, they use their laptops and code to help people.
