The thing is, the current version of Gutenberg is not a bad editor for writers and editors and absolutely the way WordPress needs to go to stay relevant. If Matt did one thing right in the last couple of years, it was realizing that. The way he went about it, seems to have been not always the greatest, but it's an absolute must.

And ClassicPress is the fork of Gutenberg deniers who think a, now, below-average WYSIWYG editor is the way... or...

all the alternative "Page Builders", which are in itself a multi million dollar business, and are horrible usability & code-wise. The two newer big ones, Brick and Breakdance seem fine, but are much more complete website builders than editors. And also something that you don't want end-users to touch.

Don't see that fork being the future.
