This is a problem on all sides. On one hand, Yes, the producers need the funding to keep producing high quality -and very expensive- reporting. If Google and Facebook simply stop linking to actual news then the revenue those orgs depend on will dramatically decrease. Further, then the only "news" most people will see will be cheap opinion pieces. News orgs have long loved opinion editorials because they are really, really cheap to produce -and are really quite popular. If this goes through, then you will see investigative reporting drop even further.
