Is the salary earned from working in a media company that broadcasts various channels, some of which are forbidden and some permissible, lawful or unlawful?

Working in the field of telecommunications is permissible in principle, but if it leads to that which Allah has forbidden, then it is unlawful. If the company primarily deals with corrupt channels in most of its work, then it is not permissible to work there. However, if it deals with both corrupt and permissible matters, there is no harm in working there, unless one is assigned work related to the corrupt channels, in which case it is not permissible due to it being cooperation in sin and aggression.
