agreed! i also use Notion for my thesis lolooff... I understand if they want to take a break after experiencing that tragedy...
Though I'm not sure why author won't save their important data on something online. Like I am writing my game's script on Notion, I also noted down my plot stories, character profiles, literally everything on my Notion. The good thing is that Notion is free, and you can access it through mobile or PC.
... I am not advertising Notion btw.
some people are also suggesting that this might be an april fools' joke—i totally forgot it was a thing, so i hope that's the case
