Thinking about it Section 230 is not such a terrible thing.
The problem is not REALLY that Big Tech is tacitly editorializing. What they are REALLY doing is playing the role of Political Action Committees. They are engaged in active political advocacy, having swung by one account 6 million votes.
So I would suggest that if they do not straighten up they should be regulated as PAC’s, and some proportion of their advertising revenues treated as political contributions.
I do not know the law, but I think a clever lawyer could make this work.
That would be both cleaner and more honest than revoking 230.
