I agree, Sky News seems to be the only sensible media outlet, but often blocked by Facebook and Google as fake news.
I disagree that content platforms should be regulated, unless ran by the government. If they advertise to be open, then block conservative outlets like Facebook/Google does on the regular, they should be held to truth in advertising laws. If they want to admit their bias, then that would be totally fine with me, as long as they are honest.
Governments however should not be allowed to do business with companies that admit their biases to avoid government truth in advertising laws, if you say you are a left-wing oriented site, you get no money. This would put a damper on Amazon and Google cloud products if they wanted to block eg. Parler from their systems, then no government contracts for you.
