These are great points.

I dont see why the FBI wouldn't buy Pegasus. Does the above poster think the FBI can just call the NSA and tell it to decrypt a bunch of stuff? The NSA has its own mission and its based on national security interests, not solving the everyday crime the FBI works on. The government isn't just one big club. I'm guessing its likely the NSA isn't going to offer up its best tools to catch someone providing abortion access in Texas or "stealing" academic papers from JSTOR or "pirating" comic book movies. Not only is it a waste of their resources but every time a tool like this is used, the detection of that tool is possible, and with that detection Apple or whomever would figure out what the exploit is doing and patch against it. Now that tool is wasted because some FBI boss wanted a promotion thinking if he impersonated an Associated Press journalist to hack a teenager again like they did in 2007 it would impress some authoritarian higher up.

They can't waste these precious exploits on some culture war, IP enforcement thuggery, leftist organizers, unions, and mid-range drug dealers the FBI regularly beats up, murders (think Filiberto Ojeda Rios), harasses, and spies on. Even the NSA is low-key ACAB. So they just say no and tell the FBI to just let NSO potentially burn their exploits. The NSA and military intelligence has better things to spend it on (think Stuxnet-like scenarios).

tldr; the FBI operates on a level far below these other organizations and are far less important than any of them in the grand scheme of things. They're just well funded cops with all the problems cops bring. They're not getting NSA tools because they don't need them the same way your county sheriff doesn't need MRAPs to drive around in.
