I think the article rightly speaks of "trust-erosion" in connection with this incident because, in addition to the showing of ads being subject to the suspicion of surveillance, it raises the question how seriously we can take a wallet app that shows ads or does anything completely unrelated to its designated and propagated purpose, something that is not the reason why this app is used and in fact detracts everyone from the intended use of this app.

The breakdown of trust is already in the question "What absurdity comes next from such a sensitive app?"
