Let's asume I wan't to use software X. I notice software X is open source.

How do I validate that said software doesn't do shady stuff?

Is there some kind of platform which lists the audits of each software or alerts the internet if shady stuff happens?

I know about alternativeTo.net, where you can find software alternatives with licencing filters. (Which is great btw) but I'm missing proper validation of open source software...
