Twitter hit Trump with a 12-hour suspension on January 6 over three messages he sent continuing to insist the election was stolen from him the same day a mob of pro-Trump supporters stormed the Capitol in a siege that left at least five people dead.
In the series of tweets, Dorsey also advocated for more open and decentralized approaches to developing social media standards, citing Bitcoin as an example of a technology "not controlled or influenced by any single individual".
He also said the ban was in part a failure of Twitter's, which hadn't done enough to foster "healthy conversation" across its platforms. And a time for us to reflect on our operations and the environment around us.
We are trying to do our part by funding an initiative around an open decentralized standard for social media.
"We made a decision with the best information we had based on threats to physical safety both on and off Twitter", Mr Dorsey said.
His statement also cut little mustard with U.S. conservatives, who accused him of obfuscation and of applying different standards to Mr Trump than to rival leaders such as Iran's supreme leader.
Donald Trump's Twitter account was suspended last week. I also recognize that it does not feel that way today.
Dorsey concluded with, "It's important that we acknowledge this is a time of great uncertainty and struggle for so many around the world".
'After careful review, and in light of concerns about the ongoing potential for violence, we removed new content uploaded to the Donald J. Trump channel and issued a strike for violating our policies for inciting violence, ' a YouTube spokesperson said in an emailed statement. His attempt to overturn the election may have done just that.
Some conservatives fled to other social media platforms, particularly Parler, which was then blocked from iPhones by Apple, blocked from Android phones by Google, and taken offline completely by Amazon. Having to take these actions fragment the public conversation. I do not believe this was coordinated. More likely: "companies came to their own conclusions or were emboldened by the actions of others", Dorsey said of the tech companies' actions. 'This moment in time might call for this dynamic, but over the long term it will be destructive to the noble goal and ideals of the open internet'.
Yes, we all need to look critically at inconsistencies of our policy and enforcement.
He did not make specific mention of his own accounts being deleted from Twitter, Facebook and Instagram after his posts were deemed to be encouraging violence. German Chancellor Angela Merkel also warned through a spokesman that legislators, not private companies, should decide on potential curbs to free expression.
