After Italy, Canada has also launched an investigation into OpenAI. On April 4th local time, the Office of the Privacy Commissioner (OPC) of Canada announced an investigation into the chat robot ChatGPT development company OpenAI, which involves allegations of "unauthorized collection, use, and disclosure of personal information by OpenAI". Currently, OPC has not disclosed any further investigation details. A privacy commissioner at the agency stated that artificial intelligence technology and its impact on privacy are OPC's priorities. "We need to keep up with rapidly developing technologies and stay ahead, which is one of the areas that I am focusing on as a privacy commissioner."

On March 31st, the Italian Personal Data Protection Agency announced a ban on the use of chat robot ChatGPT from now on, restricting its development company OpenAI from processing Italian user information, and starting an investigation. The Italian Personal Data Protection Agency believes that on March 20th, there was a loss of user conversation data and payment service payment information on the ChatGPT platform. However, the platform did not disclose the collection and processing of user information, and lacked a legal basis for collecting and storing a large amount of personal information. At the same time, the agency also accused that although the service claims to face users aged 13 and above according to OpenAI's terms, it did not use any filtering mechanism to verify the user's age. However, currently OpenAI has sent a letter to the organization expressing its willingness to cooperate, expressing its willingness to respect European privacy rules to reach a solution. The two sides will hold a meeting on Wednesday evening local time. With the popularity of ChatGPT in multiple parts of the world, more and more countries are concerned about the potential threat it poses. According to Reuters, Germany may also follow in Italy's footsteps to "block" ChatGPT, due to data security issues. In addition, privacy regulators in France and Ireland have also stated that they have contacted Italian data regulators to discuss their investigation results. A spokesperson for the Irish Data Protection Agency (DPC) said, 'We are following up with Italian regulatory agencies to understand the basis for their actions, and we will coordinate this matter with EU data protection agencies.' Not only national regulatory agencies, but AI professionals have also launched an 'attack' on ChatGPT. In March, Tesla CEO Elon Musk and several AI entrepreneurs, scholars, and executives jointly issued an open letter calling for a global halt to the development of GPT technology for at least six months. The letter points out that AI developers must collaborate with policy makers to accelerate the development of a strong AI specification system. It is worth noting that at this juncture, ChatGPT announced the temporary closure of its $20/month Plus paid service, which the official website explained as "high demand". At present, OpenAI has not publicly stated when the Plus paid service will resume.
