This is why you do 3-2-1 backups. If you've ever worked for any company, you should know that eventually budgets will get cut, and the service will degrade until something breaks. It doesn't matter whether you're dealing with some family run small business, or the world's largest and most advanced tech company. No system deserves absolute trust, especially long term. I personally rotate 2 local, and 1 or 2 separate cloud providers, depending on how important the data is. Everything not shared is encrypted locally.
