Author here, sorry if this was not clear: that specific point was not supposed to be an indictment of all CRDTs, it was supposed to be much more narrow. Specifically, the Yjs authors clearly state that they purposefully designed its interface to ProseMirror to delete and recreate the entire document on every collab keystroke, and the fact that it stayed open for 6 YEARS before they started to try to fix it, does in my opinion indicate a fundamental misunderstanding of what modern text editors need to behave well in any situation. Not even a collaborative one. Just any situation at all.

I think it's defensible to say that this point in particular is not indicting CRDTs in general because I do say the authors are trying to fix it, and then I link to the (unpublicized) first PR in that chain of work (which very few people know about!), and I specifically spend a whole paragraph saying I hope that I a forced to write an article in a year about how they figured it all out! If I was trying to be disingenuous, why do any of that?
