And it's a philosophical idea from the beginning, and everything is engineered into that.

And it's a culture, right?

And so, for example, and VLC became very popular on that because a long time ago when people were pirating content, which they do a lot less today, and none of us ever have.

The metadata to play some files like a VI is at the end of the file, right?

And when you're downloading, you don't have that, right?
