A while ago I announced here that I would be speaking at a GraalVM workshop / conference. There was a slight misunderstanding. This workshop is part of an academic conference and they want me to pay them to give a talk. I said I won't be doing that, so now there won't be a talk. Hope they will find a nice submission to fill the slot.
This might be more common in academic settings. But I'm not going to spend several hours on a talk for which I have to pay to deliver.
What is that conference?
Bummer! But totally understandable why you bowed out!
Just to be clear. This conference isn't organized by GraalVM / Oracle but by Twitter and isn't independent from the larger conference.
