I'll bring some context to this.

When I moved into using SPDX, I took the example from places where I saw
also the copyright using "//". That's the reason for the choice.

I.e.

$ git grep "// Copyright" | wc -l
2123

I don't care, which one to use, just wondering is it done in the wrong
way in all these sites?
