Other than what I post on Hive and the couple of other social networks I use, which is very little, I don't put anything out in the cloud anymore. I used to actually defend iCloud until recently because from what I understand, things have changed a bunch over there in the last 5 years... I put everything on external hard drives with multiple phyiscal backups, stored in multiple locations and have taken it off of all cloud services.
The next big move will be to start taking all my websites off managed hosting platforms and try to self-host them. But I am just one guy without much reach, so I can only be an example. It's a problem with blockchain validators and witnesses as well. Many use these big data centers to run their nodes, which can be shut down at any time. Even something like Privex is a central point of failure, just to give a Hive based example.
But there are projects like Akash that actually run things in a decentralized way using blockchain. This has been an option I have looked at as well for my website hosting becuase you apparently can build Wordpress sites on it.
