I get Linux from people I trust to verify source code and the source code of dependencies and to push back against dependency sprawl (Debian, in my case, and I'm on debian-devel and I happen to see every email sent for every new package; there's an overhead there). Others get Linux from a vendor they have a commercial relationship with (Red Hat, Canonical, even Oracle, etc.)

So, can you expand on why you think one should never run Linux?
