Twitter is there to make money for its shareholders by showing ads to regular users in exchange for cash money.
Elected world leaders play a critical role in that conversation because of their outsized impact on our society.
World leaders are a cash cow for Twitter, who doesn't give a hoot about how they came to power. I doubt they'd deny an account to a Saudi prince, for example.
Blocking a world leader from Twitter or removing their controversial Tweets, would hide important information people should be able to see and debate. It would also not silence that leader, but it would certainly hamper necessary discussion around their words and actions.
These two statements are mutually exclusive; if leaders are dependent on Twitter to get information out (they're not) then it ought to be run as a public utility in a truly open fashion. Meanwhile, someone being on or off Twitter would seem to have little impact on other people's ability to discuss their doings on Twitter.
But if we're to accept Twitter's stance, then political leaders ought not to be able to delete their tweets, since the purported necessity of seeing and debating them is undermined if they can retroactively edit the record of their own public statements.
We review Tweets by leaders within the political context that defines them, and enforce our rules accordingly.
Twitter is absolutely not going to mess with anyone who could seize any of staff or assets by force, but would like to retain a shred of dignity.
No one person's account drives Twitter’s growth, or influences these decisions. We work hard to remain unbiased with the public interest in mind.
Please think of Twitter as a public utility even though it is actually a for-profit business with a PR problem.
We are working to make Twitter the best place to see and freely discuss everything that matters. We believe that’s the best way to help our society make progress.
NYSE: TWTR has been in a 2 year trough since falling to ~1/3 of its 2014 high and would really like to like to have and eat its cake simultaneously, pretty please.
