Based on what evidence? And is the "signal to noise ratio" (I guess something like the ratio of "impressions" containing all true vs. at least one false statement) really measuring anything useful? And need that necessarily be the case? Now information which used to be difficult, expensive, slow, etc. to obtain is accessible to all people with internet access within seconds should they ever try to find it.
