Agreed on point 3 for modern editors in 2022, as real-time collaboration and collaborative editing are table stakes today if you want to compete. But to give EN credit, when they launched (web 2008?) this was not the case, and a complete rewrite on point 1 could very well be necessary when the new CEO took over recently.

We started with OT [1] in mind for V1 of Taskade [2] with the intention to make our editor collaborative, but it was still a bumpy road before we were able to iterate on the product and speed up our dev cycle,. It continues to be a challenge to support the various use cases and customers, as improvements for offline editing, cross-device syncing, and recovery never ends.

This problem isn't fully solved and there are no perfect out of box solutions.
