That may all be, but restricting the platform's own freedom of speech would serve as a governmental chokehold on speech above and beyond what a publisher can do on its own.

That is the issue that I also struggle with too. I don't trust corporations to be the arbiters of free and fair speech, but I certainly don't trust the government with that task. Especially since this is a global issue.

Historically both the government and media conglomerates have shown themselves to be rife with corruption and abuse.

but what is the real solution for this?

Honestly, I don't know. I can't see a winning solution, I just hope that somewhere there is someone smarter than me who can find a happy compromise.
