HoloLens has been seen and used outside of the company, however. They have been touring several cities and showing off Hololens units to developers. I am not an MS employee, but I did get to try it out and do some Q+A with Hololens developers.

I don't think any magic leap units have ever been used by those outside the company, but I'm excited to see what they come up with.
