(EU+UK) Legal theory that closed-source software inherently undermines or violates the GDPR in some situations

cross-posted from: https://beehaw.org/post/12170575

The GDPR has some rules that require data controllers to be fair and transparent. EDPB guidelines further clarify in detail what fairness and transparency entails. As far as I can tell, what I am reading strongly implies a need for source code to be released in situations where an application is directly executed by a data subject and the application also processes personal data.

I might expand on this more but I’m looking for information about whether this legal theory has been analyzed or tested. If anyone knows of related court opinions rulings, or even some NGO’s analysis on this topic I would greatly appreciate a reference.
