Solved linux-crashplan not found in pkg

Why are some packages not found in pkg? Fresh Ports shows the exact command usage as pkg install linux-crashplan, but it's not found and I still need to compile the port manually.

I'm running FreeBSD 11.0, am I missing a mirror or something?
License probably prevents re-distribution. That's usually the reason why there's no package. The page on Freshports is just a template that shows information from the Makefile.
