Fairly obvious if you read through their "promise": > We promise to do everything in our power to ensure that any content you publish on the platform will continue to be available on the web forever, at the same permanent link, as long as you want it there. If the company stops existing, there is no "We" anymore so realistically, they don't have to continue trying. If all of them gets hit by buses (or all by the same bus), I think it's reasonable to say they did everything they could in their power, but their power is now non-existing so probably you content will be soon too.
