There is a good case for some sort of in-sourcing when it comes to national systems. For example if, say, a Chinese diplomat toddled on over to you (let's say you are a US citizen and an important one) and asked you to use his country's foremost VPN solution for secure communications. Would you?

Now let's muddy the waters somewhat. Zoom? sounds a bit Anglo/Sax ... ish. It isn't of course. It also seems that Zoom forgot to encrypt their encrypted channels. lol.

There's more to security and stuff than cash. I do the boring old security thing for a living. It is boring but I like boring.
