Re: Always listening to our customers
If you have access to masses of private communications & other data, and the means to run it through complex algorithms, there is also a huge temptation to search for things that will make you money or give you power rather than merely things that are a threat to the country. And if the whole process is secret, there is little risk of being caught doing so, and so the probability of it *not* being used for those things is practically zero.
Data is power. Power corrupts.
