I read an article that a married couple who stole bitcoins worth several million-billion dollars kept a private key in the cloud and nothing happened to it.
What's your point? That it's OK to keep seeds, private keys, and other sensitive information in the cloud because a married couple somewhere didn't have theirs hacked/stolen/lost? You can drive your car 100 miles/hour every day without a seatbelt and never have an accident if you are lucky. But you can also crash and die the first time you do it. You can smoke for 50 years and live a long life and die an old man at 85, or you can get cancer and die at 30. You don't use those examples to cheat on security and your safety. The goal should be to follow proper procedures to lower the chances of bad things happening to you, no matter if it's related to your personal health or your financials.
