Ghidra was about hiring and cost savings. Its easier to hire when people already know your tools. Also people are more willing to use your tools rather than expensive ones if they can still use them when they leave (go into contracting). Also interoperability with contractors may improve.

No idea. I just use the yubikey ones. I have an old usb-a oneb and a newer small usbc one
