Broadcast licenses are for “public convenience” The licensee must show that they serve the public. These Alphabet networks are not doing that because of their bias. Their license to broadcast should be rescinded.
That is the BS liberals try. The MSM are dying of their own accord. No need to try using government to silence them.
My working hypothesis is that the "progressive" take over of the main stream media could not have happened without the requirement for licenses. I think that the reform should be to sell off the air space so that it is private property. There is money to be made in giving news without the "progressive" agenda. The MSM makes decisions to put agenda over profit every day.
Consider the whole public broadcasting system aka the propaganda broadcasting system. It is a disgrace to the first amendment that there is a government broadcasting system at all.
