Given how politics and companies evolved, I actually trust those people in charge of XKEYSCORE systems more than ever. They may wear suits, but those people usually come from some military background, and have a sense of duty towards defending US, from threats both foreign and domestic, and historically have not really abused their powers no matter what the administration is. XKEYSCORE for example, wasn't really about hacking people, it was just about collecting mass metadata and building profiles, well within the legal system, and the blame should be on the companies that didn't provide privacy tools, because any big government could have build the same system.
Meanwhile, the anti anti-establishment Republican Party since 2016 who cried about big tech turned out to be the biggest pro-establishment fans, giving Elmo an office in a white house and Zucc bending a knee to avoid prosecution.
With these new systems, Id rather have smart people who only work in US defensive forces because of a sense of duty (considering they could get paid much more in the private sector) in charge.
