Hypothetically speaking, what if the said company acts with ulterior motives, is blatantly anti national, blatantly trying to interfere in elections, cause riots etc. What should a responsible government do then? Hypothetically.
Blatantly trying to interfere with elections -> if you mean by spreading opinions / propaganda, this seems generally under the realm of free speech. The government being able to silence opinions that disagree with it generally seems much more problematic than civilians being able to spread bad opinions
Cause riots -> Again, I think opinions should be legal. However, saying "hey y'all let's get guns and actively participate in violence" is not protected under free speech in any country I'm aware of, but is also not really my major concern with this legislation.
