What happened with Zas Editor?

Just a few months back this was on frontpage of HN: https://news.ycombinator.com/item?id=30952084. It looked like a promising new text editor but the website https://www.zeditor.app doesn't exist anymore.

Did anyone purchase it? I am curious if the project got abandoned because it did not get much traction or if it was some sort of scam.
