To start, large social media companies should be required to become interoperable with one another: Just as you can email someone who uses a different email provider than your own, you should be able to contact and engage with individuals across different social media platforms. In the same vein, large social media companies should be required to permit the use of alternate filtering and sorting algorithms — democratizing content moderation by allowing users to choose which content they wish to view or block, rather than relying on the black-box internal processes of an individual, hyper-concentrated company.
Agreed, except that the first point is potentially in tension with the second. Perhaps micro.blog should be forced to become interoperable with Twitter, but I should also be able to set my micro.blog account so that I will never see anything that anyone on Twitter says to me — which is precisely the setting I would choose.
