These tools/procedures are widely used for other reasons including at border crossings. They get training to use it. Law enforcement also often uses them illegally for unjustified search and seizure targeting those who have done nothing beyond crossing a border or journalism. The groups of people using tools from Cellebrite or competitors are often the ones breaking the law or using them for criminal reasons. Many of the people using these tools are criminals breaking the laws of the land.
Even if they say it's only for certain governments and law enforcement clients, it doesn't and won't stop them getting out. There are likely militias, juntas, or criminals in the world with access to these tools as long as they are powerful enough. If Cellebrite isn't available somewhere, something else will take it's place. If we can get documentation, someone far more powerful could get far more.
Defending against tools like these being only valuable to the criminals is a narrative for authoritarianism. Don't let them attack you this way.
