Perhaps not the cyberattack.
Were they on a path to going bust anyway, and the cyberattack just sped it up? Almost any company with a pile of debt would have had trouble coping with the post referendum inflation we have had. When your currency goes down 25% overnight, in a world where everything is priced in USD, the result is seismic. The government and media can cover it up, give it a fancy name - the cost of living crisis, and blame it all on Covid and Putin, but at the end of the day, the impact will still happen.
If you cannot secure your tech, go back to using people, phones and paper. You will be more resilient. We have been doing things this way for decades, and it generally worked. Shifting your reliance on to expensive tech (expensive because you have to keep updating it every few years to keep GAFA rich) is not always a good idea. Loads of small businesses use limited non-networked systems and paper for their day to day operations, with good reason.
