What is the ruling on knowledge gained from non-original computer programs, according to those who deem their use forbidden? Is it knowledge that is not beneficial or deprived of blessing, or is it impermissible to share it with others?

The relied-upon fatwa is that software copyrights must be respected, so it is not permissible to use pirated software. However, there is no harm in benefiting from the knowledge gained through such software and in benefiting others with it, while ensuring the rights of the software owners are protected. Generally, religious transgressions are a cause for the removal of blessings. Therefore, it is not improbable that software piracy is among the reasons for the lack of blessings in the knowledge gained from it, even if this is not necessarily a definitive conclusion.
