I have never seen that interpretation. Tainted is a synonym for contaminated.
Contaminated doesn't mean that it doesn't work, it means that you should
exercise caution in using it (e.g. you may not want to drink it, but you can
use it to wash your car).

</I>
There is something wrong with the package, it is contaminated by software
patents.
