I am really surprised they don't do much against Pegasus though. I'm sure the agencies involved know what exploits it uses by now.
I guess because western powers use these tools too is why they don't lock them out.

I wouldn't be surprised if it hasn't always been at full effectiveness on all platforms, as vulnerabilities are patched and others discovered.
