You're generally right about the vulnerabilities that might be present in both open-source and closed-source software. However, there is still a difference between the two. Closed-source code may contain both intentional and unintentional backdoors while open-source code is less likely to include intentional backdoors, simply because developers know that their presence is likely to be discovered by the community,
sooner or later.
I think it's a bit of terminology.
Open source should be considered SAFER since you (or someone) can check to see what is happening. If you (or someone) understands the code.
This would prevent the send all coins to Dave issue.
But, you can't really say it's more *secure*.
A bit pedantic on my part but when dealing with customers I have to point things like this out.
In the end discussing it here probably does not matter as much, but when talking to non tech people it's probably better to make the distinction between safer and secure.
