Well not quite that either. I don’t know how to pack this up into a tidy analogy, but the issue is that some of these communication platforms have been designed in such a way that no record of the content can be accessed by a third party.
So maybe it’s more like, “Please give me a transcript of the keynote speech at your murderer’s convention,” and replying, “Sorry I don’t have a transcript.” And then the government further saying, “Well then you need to let us install bugs in all your rooms,” and you, the host of many different conventions reply, “No. Privacy is part of the service.” I have now belabored this analogy to death. You’re welcome.
It would be nice to have some opposition, though. Even if most “conservative” media right now is little more than xenophobia, or cult worship, there do exist sound arguments against the typical internet-left positions. I don’t have a solid enough read on what comes through New in the fediverse to say whether any of that is being submitted and just downvoted off everyone’s feeds, or if all that’s being submitted is the average conservative media junk.
Still, political spaces without opposition/diversity invariably degenerate into purity contests, and circle jerking.
