This is why many professional journalist were peeved with Greenwald when he presented the exact same experience all journalists face every day as a normal part of their job as censorship.
That's one version, but another way to interpret it is left-leaning journalist outfits made the 2016 mistake of focusing too much on Julian Assange and the emails fiasco around election time. In their minds, that cost Hillary the election, and they didn't want to do the same thing again with Biden and his son's laptop. And seeing as how virtually no left-leaning publication reported on it, this seems the more likely version of events.
