I completely agree. My point is: if captchas don't help then why would
pasting commands from the net help to get the user think about the
risk their actions imply?
My opinion is clearly that we should come up with a decent and
standardized way to add third party applications that we can actually
_control_ and design in a way that at least gives our users a chance
to educate themselves before taking any action.
If you just ignore the demand to install third party applications from
third party repositories you will likely train our user-base to just
google the internet and follow arbitrary instructions they find - which
can't be what we want.
