Those repositories are used by a very small minority of users, which are also highly competent and constantly looking out for scatchy things. Yet, those scatchy things do happen occasionally on small scale be. But it's kinda obvious that the lack ob a big and serious actor is the main reason why nothing seriously bad ever happend in linux-land so far. Everyone switching to Open Source would change this and the watchmen would likely be unable to protect their world. I mean just look at the mildly bad things happening on mainstream-systems, which everyone knows about and still ignores them, because "that's just how it is". At the end people willingly use bad software & services, because their subjective gain is higher than the small price they pay.
