There is no turning back for Twitter now. The only way out is through.
But even Twitter may not have guessed that the official White House Twitter account would then choose to repost the same language hours later in an apparent attempt to further test Twitter's limits.
Having already made its position clear, Twitter really only had one option: It added a warning label onto that tweet, too.
The back-to-back incidents capped off a rocky week in which Twitter's decision to place warning labels on two Trump tweets set off a presidential firestorm that culminated in an executive order that seeks to punish the entire social media industry.
Twitter now finds itself in an unprecedented position. For years it was Trump's favored platform; now Twitter is locked in a war with the president simply for choosing to enforce its policies. Seemingly every tweet on the platform — those from general users and those from Twitter employees — are being scrutinised anew.
Republicans are coming after it. Rivals are throwing it under the bus or staying silent. Fact-checking organisations are calling for greater transparency.
And there is no end in sight.
