easier but you get less data. There's thousands of small knees to get to bend to. More points of failures for public outings Centralizing it to one company makes everyone's lives easieer.
Furthermore the NSA/FBI/CIA want all their spying behavior to be secret. If you have to bend a lot of small knees then someone's going to fib before they get the data they want. And moving off a small company that's bent the knee is way easier than moving off FAANG, which can keep secrets[0] and has your balls locked in a vise.
[0] Because, among other things, the whole "Surprise and Delight" doctrine demands internal controls and secret-keeping discipline not that far off from an actual intelligence agency
I don't agree. NSA can hack/pressure smaller companies much easier than a giant like Apple.
