My point was that an open-source program cannot rug-pull its users without the obvious remedy of forking the project and removing the offending code. Open-source: commonly seen. Closed-source: not possible and often illegal.

For both options, you have to trust the source, which makes that a non-issue. You can checksum the Linux kernel to satisfy yourself that it came from a trusted source. You can checksum the Windows kernel to satisfy yourself that you're about to be screwed.

> But that's my point - open-source doesn't really change the equation there unless you are actually auditing the source and building & running said source.

In the open-source world, knowing how computers work is essential. In the closed-source world, knowing how computers work is somewhere between pointless and illegal. This is how open-source "changes the equation."

Modifying open-source code is welcome and accepted. Modifying closed-source code breaks the law. Take your pick.
