It might be. The library my banking app uses is called Promon Shield. It was broken in 2018 as part of this paper: https://obfuscator.re/nomorp-paper-dimva2018.pdf https://obfuscator.re/nomorp-paper-dimva2018.pdf > Promon Shield protects most of the banking apps on the German market. As of April 23, 2018, four out of the top ten financial apps in Germany make use of Promon’s solution. I'm switching banks now to find one that lets me use my non rooted phone in peace. As for why? I'm not sure. My guess is to prevent clueless people running their banking app with malware installed. preventing roots might just be a side-effect.
