No, they're not depriving you of any opportunities to verify. They're offering you a shortcut if you decide that you trust them enough to forgo examining thousands of lines of code. If you decide you want to review the code, just wget it down and then install it after you review it. And if someone doesn't know enough command line to do that, are they really going to be in a position to audit the code?
