unfortunately, FOX does not...as proven with their admitted lying about a "Stolen Election", in violation of their own published "Standards of Business Conduct" (see link)...from those "Standards"...
--------------------
Our foremost principles are the ACCURACY OF INFORMATION,
clarity of opinion and quality of our content. To ensure this, we maintain strict separation between revenue sources and our news reporting and editorial opinions. We provide a platform for diverse perspectives, voices and views, always supporting relentless reporting and bold thoughts and opinions. We are innovators in sophisticated newsgathering methods, always searching for new ways to inform, engage and inspire audiences in both traditional and new media. (emphasis mine)
--------------------
Thankfully, as you point out, the majority of news media are ethical and reliable and only a minority are not...unfortunately, too many subscribers are not able to discern the false statements of that minority.
You call the "MSM" biased...one thing for sure...they are FACTUAL and ETHICAL...FOX clearly isn't, and given the volume of similar lies from other Right Wing outlets, they aren't alone in lying to their subscribers.
