The question is, if media centralization continues, what evidence/perspectives could have been removed from the public sphere, and what impact could that have on impartiality? Tech has the potential to decentralize power. Alas...
My point was: This is not really censorship. They appear to censor, appease their advertisers, but actually they are amplifying. That is in their (Facebook) economic interest. If you decentralize you will end up with a media for each particular group, and you will have less engagement as you are only discussing with people you agree with.
In censorsing they might have amplified the story, but this amplification only occurred after the matter/case was decided. That is too late.

This already happens with centralization, as the OP raised. Multiple groups at least offers the choice.
