I think you have it the other way around. The bias is institutionalized so deeply that the process makes it essentially impossible to get a non curated with bias point of view out of the organization.
Look at how tightly political leanings are tied to news outlets.
If it were as easy and objective as you say we would get a lot more random pieces out of outlets instead of the rather rigid ideological publications we see in existence today.
Even Reddit subs and hacker news, which are much more random than news outlets, have pretty clear political leanings. With sufficient samples you can even break down the subgroups within the community.
News orgs don't have nearly the internal diversity required to possibly remove such bias. They are homogenous.
