I think the author was being a tiny bit hyperbolic saying "nothing really matters but value for the customer". In a restaurant kitchen, the goal is to get food into the customer's mouth... but you still want to keep your knives clean and tidy. Of course, keeping them tidy isn't the point of the restaurant either.
But you can still use 1Password even if the service is temporarily disrupted. You have a local copy of your data on each device, so you can work when you are offline. It's just that your vault is stored in the cloud, so syncing could be disrupted. This thread's headline is misleading IMO.
