no, this shows incomplete understanding of layering in a modern operating system. Closed-by-default software projects, over time, are less secure; common source code components make a stronger system over time when executed well; secrets can be handled in a secure manner in security-sensitive applications; well factored software using modern layers are more secure over time with common, tested software components.
