*A US surveillance program tracks nearly 200,000 immigrants.* It collects a lot of data, including their locations all the time, and the data can be abused by the government or the company that runs the surveillance system.

No company should ever be in practical control doing the state's computing. Privatizing any government activity makes it unaccountable, and that's part of what we are seeing here. The extra level of indirection in control of the procedures (and the software used) has the effect of thwarting the people's control of the state.
