You don't need to. If it's open source, it's open to billions of people. It only takes one finding a problem and reporting it to the world
There are many more benefits to open source:
a. It future proofs the program (many old software can't run on current setups without modifications). Open source makes sure you can compile a program with more recent tooling and dependencies rather than rely on existing binaries with ancient tooling or dependencies
b. Remove reliance on developer for packaging. This means a developer may only produce binaries for Linux, but I can take it and compile it for MacOS or Windows or a completely different architecture like ARM
c. It means I can contribute features to the program if it wasn't the developer's priority. I can even fork it if the developer didn't want to merge it into their branch.
Regarding point 2. I get what you’re saying but I instantly thought of Heartbleed. Arguably one of the most used examples of open source in the world, but primarily maintained by one single guy and it took 2 years for someone to notice the flaw.
No more or less relevant than heartbleed. Yes vulns exist in open source software, sometimes for a while. Being open source can lead to those vulns getting discovered and fixed quicker than with closed source.
And how does this negate my initial point that you shouldn’t trust in the security of something just because it is open source?
I think you misunderstood what I was saying.

Uhh... so? The NSA was sitting on the vulnerability for EternalBlue in Windows for over 5 years.
Dont understand what that has to do with the discussion so far. How is this relevant here?

Alright then, have a nice day!
