Imagine living in China,
where the government is able to request data of each company in their country.
Imagine that China would setup an AI/LLM,
to feed all private chat data into it,
and automatically flagging opposition of the government regime.
Imagine a white van appearing in front of your house and disappearing into a concentration camp because you got flagged after expressing your opposition to the government to your mate in a private chat.
All collected data can be abused like that,
or by other means (E.g. a country at war gets hacked, which could lead to leaking critical private information on political/defensive decisions).
To me the question is not if data collected on you will be abused, but rather when will it be abused?
Just having it stored somewhere imposes risks.
Spying on you :P
That’s why I replaced it with MicroG:
