It all returns to nothing

On the fourth and final day of the 2022 canvas, an event occurred which goes by many unofficial names such as the anti-void, the white void, the whitening, the whiteout, the wipeout, France surrendering, the apocalypse, or simply the end. It marked the end of 2022's canvas.
==2022==
On the fourth day of the canvas, the palette was reduced to a single color: white. Naturally, the entire canvas started turning to whiteness, starting with the botted French area, the osu! logo, the blue corner, and any other areas where a project was in-progress. Any and all characters that weren't overrun entirely started leaking white from their eyes. The final 2022 builds on were thus last-ditch attempts to make something purely out of white: the word "FRANCE" which only made it to FRA8, the German word "DÖNER" which instead became BONER, a random letter "S", the word "osu!", a giant white crewmate out of the A in the aforementioned FRA8, a stripe expanding from the blue corner to the top-left, and, finally, a giant white heart starting from the bottom-middle that expanded until it hit the word BONER. By the time the heart collided with the BONER, most had accepted it was the end; with no way to correct mistakes and a white mass appearing from the top-left whether the artists wanted to place white pixels or not, the entire canvas was empty in a matter of hours.
Canonically, this event was most likely caused the second void monster that was preserved by artists on the bottom half of the canvas. As it was only possibly for this monster to reveal itself thanks to new empty space being added to the canvas, it was arguably a harbringer of empty space from the beginning, and as it is an eldritch abomination, the power needed to remove everyone's colors doesn't seem outside of the realm of possibility. Additionally, its eyes started expanding rapidly as the event occured, a sign that it was activating its power. This also explains why the 2017 canvas did not end with a similar event, as there were no void monsters created on it (let alone preserved intentionally).
Narratively, the event unified the whole canvas under the message of impermanence that had been touted by the void even during 2017, a message already made apparent by 2022's rampant sobering reality of streamers overriding anything they want whenever they want. It can also be considered an example of the "bookends" trope, with the canvas ending the same way it started, completely blank. Otherwise, the behind-the-scenes explanation is probably the best one: it was a very fittingly cruel finale to the April Fools' Day joke and social experiment that is /r/place, successfully subverting people's expectation that there would be final work of art in the end like 2017, which is the assumption everyone had been working so hard under. Of course, many /r/place participants have rebeled against the message of impermanence that this event brought to the canvas by creating their own preservations of what the canvas looked like prior to this event and touting it as the "final" canvas. But in the end, it all returns to nothing.
