Yes, you're right. I failed to keep a full perspective when I wrote that. I won't defend that.
I do feel it's significant that it took about a month from the sharing on that minecraft server for these leaks to be recognized. I'm surprised no one on the server flagged it, or it wasn't picked up by some intelligence program. That's where my shock came from. It feels like a deeper problem. Maybe I'm naive in believing the military/intelligence community didn't know before this news broke.
Yup, IMHO what was leaked in this case is not so important. What is important is how it was leaked, how long it was leaked for, and how long it took to notice.
Lots of people in the comments here stuck on the boring semantic definition debate of mocks vs stubs vs nulls vs whatever.
This is not really by what the article is about IMHO. It’s a great overview of how to grow and organize your application with some opinionated patterns that give some favorable properties to your system. The nullable stuff just helps achieve those properties. If you want to use a mocking library to write nullables, and call them mocks, fine. Not important.
