Suppressed, true. Because Government owns all the big media. So whip in hand, it sets the agenda.

KBN?…Is it that substation fronted by that pigmy who calls himself a Pan-Africanist and his beautiful women presenters as comrades? It is chaired by a failed pastor and a drunken failed diplomat

Government executes but doesn’t make the laws. Parliament does. The pharmaceutical or Aviation industry you have mentioned have regulations to protect public health and ensuring professional standards. If an unregistered pharmacist starts operating in your street he could easily poison the community so he has to be regulated.
Similar media regulation would risk limiting fundamental freedoms including yours as an individual. If government or outside bodies supervised the media this could easily lead to censorship or the suppression of dissenting voices, thereby undermining democratic discourse.

They are supervised by laws. Thats why their professional bodies are in the laws.
In a democracy, the media is part of governance. The media plays a watchdog role over the three wings of government. It also safeguards fundamental democratic principles, particularly freedom of speech or freedom of the press. The professions you have mentioned play no part in governance. They can be supervised by specific laws.

Please know the mandate of IBA instead of exposing your ignorance in public.

Who regulates the aviation industry, the automotive industry, the financial industry , who regulates the manufacturing industry, the pharmaceutical industry? It’s often the state because businesses are often conflicted as the profit motive may blind them to consumer safety.
