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?
There isn’t a clear divide between open source software and proprietary software anymore due to how complex modern applications are. Proprietary software is typically built on top of open source libraries: Python’s Django web framework, OpenSSL, xz-utils, etc. Basically there isn’t anything safe, and even if you wrote it yourself you could introduce bugs or supply-chain attacks from dependencies.
