My problem with the post isn't the solution offered. It very well may be that
it's the easiest or best solution. My objection is in SuperTramp implying
that he knows a better way that he is refusing to tell for the sake of
negative reinforcement:
"There is a fix but reinstalling the OS would be better, because it would
take you more time and effort. Why do I want you to go for the long and
difficult road of spending a couple of hours to backup, install and customize
you OS? Because that way, I guess, there is a higher chance that you will NOT
add non-free stuff to your computer in the future.."
Emphasis added.
Just imagine that you're asked by a friend to fix his car, and you tell him
that you could easily do so, but that he should get a new car anyway because
maybe the extra cost will encourage him to not break it again. You wouldn't
be friends with him for very long with that kind of attitude.
