That was hardly a one-off. Just off the top of my head...
There was the massive amount of CSAM it produced for weeks that wasn't an oopsie, the company adamantly refused to do anything about it for a long time despite the outrage.
Plus there has been all of the monkeying with the system prompt to push random propaganda elon wants.
Also the weird fixations on white genocide, election lies, and other nonsense.
On top of all that any data or funding sent to this company directly supports the ongoing destruction of US democracy and state capacity.
