I support free and open source software (FOSS) like VLC, Qbittorrent, Libre Office, Gimp…

But why do people say that it’s as secure or more secure than closed source software? From what I understand, closed source software don’t disclose their code.

If you want to see the source code of Photoshop, you actually need to work for Adobe. Otherwise, you need to be some kind of freaking retro-engineering expert.

But open source has their code available to the entire world on Github or Gitlab.

Isn’t that actually also helping hackers?
