Apparently you don't read TechDirt, which I have for over a decade now, and NSA had been active in shenanigans and lax securityy since the wiretapping scandals of the aughts, and in 2023 has been leaking stuff to FBI without warrants (which is supposed to be unconstitutional but between the PATRIOT act and the Federalist-Society-dominated SCOTUS, we may be no longer legally protected from NSA surveillance as an unreasonable search).
The FISC has always been a rubber stamp court, so it shouldn't be necessary for law enforcement to circumvent warrants for NSA information, but it turns out it's just easier using the NSA backdoor access.
I will admit to a certain degree of cynicism. When official channels tell me something is secure or handled with respect to all ethical and civic concerns, and investigative journalists tell me the opposite, I trust the journalists more than I do the official channels. But then I've been through the aughts and the George W. Bush administration when the only sources of actual facts were from foreign sources, because the native news agencies were terrified of reprisals for failing to toe the line.
It's why when people are alarmed today that the fascist autocrats are here and SWATTING their political enemies, I can only quietly sip my coffee from the corner.
