US-based conservative social network Gab caused controversy by creating chatbots that denied the Holocaust and which were seen by critics to normalise hateful ideologies and incite violence.

Gab's creation of chatbots in the names of Hitler, Stalin, Putin, Osama bin Laden and other polarising figures that provided antisemitic and white supremacist answers, denied the Holocaust, and justified terrorist attacks. 

The bots triggered a storm of protest from Jewish and other critics who accused the company of acting unethically by normalising hatred and spreading conspiracy theories and disinformation, and risking radicalisation and violence.

In response, Gab released a statement defending their stance on free speech. 'We believe in the fundamental right to free speech and the freedom to learn from history, even if it's uncomfortable or controversial,' it said.

The controversy was seen to serve as an example of the need to balance freedom of speech with public safety.
