On installing empty packages
The user decides to accept the overwriting of the installed package by an empty, non-functional package* on the false premise of getting an update. (edit: Just like an iTunes user might "update" iTunes, but in fact the only thing that changes is that it breaks the compatibility with 3rd party hardware)
Here, let me try to illustrate:
If I give you a box (edit: that is a physical box) that says "present" on it in english, and underneath that there's a whole lot of text in a foreign language. Will you try to interpret the words, or will you just open the present?
What if I've done this to you many times before, and you've never had any problems with it, you just get nice things. And all your friends that also regularly gets gifts from me have told you to open them.Would you then just indiscriminately open every gift you got from me without hesitation? My guess is yes. If you later find out that something that always worked before have stopped working, would you then think that it had anything to do with the gift I gave you? I don't think you would.This is how it works for "human beings", for non-geeks. The main target for Ubuntu.Edit: So the issue might not be that they _can_ override a package you have installed with an empty one, in effect deleting your software. The problem is that they can do this without a specific warning about it. And by "they" I don't mean Canonical/Ubuntu, but any distributor that have this power.
Let's say Microsoft went public with the fact that they can remotely remove software from anyones computer. "But it's ok, because we will only do it to remove insecure software, and you will have to accept the update through Windows update manager (or whatever it's called. I haven't used Windows in years), unless you've set it to update automatically. Trust us." Would you have no problem at all with this?
*I don't know how to say this in a strictly, technically correct way. The end result (and that's the important thing for non-geeks) is the same as if you'd just straight uninstalled it, though, if I have understood this correctly (which I very well might not have. I feel like people say a few different things about this, but the consensus seems to be what I just said. I am genuinely sorry if you feel like you've tried your hardest to tell me otherwise but it just hasn't sunk in.)
