I don't disagree.
But sedition isn't protected speech. So if they didn't ban him they're opening themselves up for lawsuits.
In no country on earth is it legal for anyone to publicly advocate the overthrow of their government. And there's already decisions on the books proving this, as well as the legal precedent of cold-war anti-communism laws.
He has been laying the ground work for this since at least last summer to hedge against an election loss. He has been sitting baseless accusations about mail-in ballots, solve he knew Democrats would be more likely to vote by mail because they took the pandemic seriously. What was the "stop the steal" slogan supposed to accomplish other than create the overthrowing of the legitimately elected president? If he had legal ground he wouldn't have needed a slogan, but just won his court battles.
No one has looked at the present election based off claims 8 months ago, people witnessed openly irregular behavior during the actual election and after.
The current fervor around silencing, labeling, and berating rather than reassuring fears and assisting in auditing to legitimize the election is a significant problem and not a healthy look.
The fact that there even is a discussion about whether what he's saying really is sedition is enough. They're a private company, that just opens them up to way too much liability. It's not their responsibility to be a platform for all sides, for better or for worse
Twitter was very happy when after vote fraud in other countries it was helping to promote revolutions, several years ago. Section 230 specifically frees them from responsibility if they behave as a platform and opens to much more liability if they decide to filter out some speech.
You should read Section 230. It doesn’t say that if you filter some speech that you have liability. In fact it says quite the opposite: if you make a good faith effort to filter some speech then you aren’t liable.
listen to his speech inciting his followers to go to the capitol. You can decide if it’s sedition or not, but the end result is undeniably an insurrection, and his words are what directly invited them to do this.
