While I superficially agree with the point, the article author states that they haven't tried the alternatives they suggest. Implementing CRDT or OT can be a complex endeavour, especially if you're retrofitting on an existing system that already has a REST or similar API. Use case is ever important, don't spend your all important time implementing a complex state sync if it turns out your customers don't do the kind of collaboration that requires it.
