On one hand I agree schadenfreude is a dangerous thing that one should be careful about how they engage in
On the other hand he wields a LOT of power over our discussions as a society because he owns a successful platform. If twitter fails it takes away some of his power to be a shithead and to shape our discussions in a way that sucks (ie, inviting everyone to be bigots and to be cruel to their fellow humans on a scale that’s frankly kinda horrifying)
