Twitter's permanent suspension of the President's personal link with the outside world leaves something of a hole for Trump, his fans and haters alike.
Trump no longer has an outlet to vent. Supporters are no longer fed a regular diet of the President's unfiltered thoughts. Opponents no longer get to send him their most withering one-liners.
There are, of course, far more serious reasons behind the social media move.
Trump had 88 million Twitter followers - about 14m more than people who voted for him last November. President-elect Joe Biden has 23.3m followers.
Twitter is small, compared to other platforms, with about 350 million users - but influential. Trump's reach amplified his voice. Still, it probably aggravates him that his predecessor Barack Obama has more followers - all 127.9m of them.
Facebook, with 2.7 billion users including 35m who follow Trump, is the largest, followed by YouTube and WhatsApp with 2b each. Instagram, used by some of the Capitol vigilantes to share messages, has 1.1b.
Facebook and Instagram have suspended Trump's accounts until he leaves office in nine days. Twitter also banned Trump loyalists in a purge of accounts promoting the QAnon conspiracy and the Capitol rampage. Google, Apple and Amazon are restricting the right-wing Parler social network, saying it has not done enough to stop the spread of posts inciting violence.
Social media platforms and their chief executives, such as Facebook's Mark Zuckerberg and Twitter's Jack Dorsey, have been under pressure from US legislators and foreign governments for a long time over their moderation policies and monumental power.
Trump's term has highlighted social media's impact on democracy. The storming of the Capitol was an eye-opening moment that demonstrated the real-world dangers.
Social media allows people to live in their own newsfeed, shutting out contrary viewpoints. It allows them to connect with the like-minded. It allows conspiracy theories to spread like wildfire. And it enables political manipulation on a grand scale.
Trump's most fervent and fringe supporters have been caught up in his baseless spin over his election loss. The collective delusion, aided by dozens of elected Republicans in Congress and allies in US far-right media, exploded before the world last week.
The tech moguls know a change in regulatory approach is likely with Democrats about to control the presidency and Congress.
The reaction to the Capitol siege is essentially a concession that the impacts of content on social media platforms should be considered.
Although disinformation has been a major problem for years, tackling it in a major way will require more regulations, ethics and investment.
The moves against Trump have underlined just how much unelected power is in their hands.
Enough to silence the Tweeter-in-Chief.
