The only way to deal with it is through splitting these companies up - that's the only constitutional way, and we must start immediately. They're too big.
They're not going to be too big for very long. Their size depends on people being there, and if they keep banning people they'll just get smaller. Once all the interesting people are banned the regular people will go where the interesting people are. They're about to have their blockbuster moment and no bailouts can stop it.
I hope you're right - I truly believe that post 2012 social media has been a cancer on society, in addition to the 24/7 newscycle. But I somehow am not as optimistic as you are. People far underestimate the power of twitter/fb/youtube.
The power in those sites is that they are not siloed and at scale, meaning you can reach a much broader audience. Parler would never be able to influence the mass market because it was so specialized - making it ineffective at evangelization. WSB would never be what it is without the platform of reddit. Going to a small specific site will not have the same power, even though I think it is better to host your own hardware and do that.
