I'm absolutely not suggesting you rely on a third party. It's very easy and preferable to pass around source code, and it's (by design) very easy to build GNU/Linux apps from the source.
Distributing binaries will absolutely bring about calls to lock computing down to 3rd party distributors because the kind of people that can't handle typing `./configure` are the same kind that will pull random maleware off of google.
No good can come from installing closed software anyway.
