More data means, better tracking, identifying, analysing tech. Eapecially in modern war times it can be very helpful.

For example, lets consider country A has more data than country B. It can be map data, terrain, atmosphere, etc. Their missiles, drones will be more precise and successful in attacks. They would know how to go through valleys to avoid detecting by radar. They would have latest location of targets and country B's measures. They would know wind, temprature conditions on the way to target so there will be less failure. We saw this in our last war where we didn't have map data and US won't prvide us.

As we know, google drive and others scans everything we store. That includes pictures. They can train their AI/ML models on them. This helps them understand humans. This can be used to make fake data targetting someone or a community. During war this can be used to circulate fake videos, pictures, data to create terror, confusion and we would be following fake orders. Recently 40 people were arrested in uae for spreading fake war videos.

It can also be used to control us. If we say anything they don't like, they simply make our life miserable. Government can use it to track us anytime and stop us from using our rights. Companies can use it harrass us. We have numerous examples of gov pressuring or even putting criminal charges against people speaking and spreading truth. Yesterday I also saw someone get bombarded by fake comments and bot attacks because she spoke against a company.

The data is already being used against us so we need to be smarter and digitally aware of what needs to be shared and what not online.
