This is true of open source software too. At some point you have to trust that the software you run is not designed to act like malware, because if it is actually backdoored your life is going to be miserable regardless.
Huh? It's not true of open source software at all.
With open source software, you can read the source and verify that it doesn't have backdoors. With reproducible builds, you can verify that distributed binaries are the result of building the source code you've verified.
Honestly, if you couldn't figure out that this was going to be my response, you simply don't have the knowledge to be commenting on this topic. I didn't come up with anything I've said here myself, it's pretty basic, widely agreed-upon understanding of why open source is generally more secure. The only people who actually know the topic who "disagree" on this generally have a vested interest in some closed-source software they want to be seen as secure.
