Among other problems, the definition of "news organization" is completely fluid in this Internet era. What organization in particular gets a truth or balance mandate? Some? All? Which ever ones the censors consider most credible?
"Does it benefit society if the only opinions broadcast as fact are filtered by corporate interests?"
Not sure how you got here. Proposing news organizations obey some "truth" or "balance" conditions essentially is mandating state filtering.
The Internet, so far, has allowed a wider dissemination of ideas than ever before. Are you saying that organizations, on the net, large and small, broadcasting their views, is "corporate filtered news?" Seems like you're stretching things to say the least.
