I’m totally in favor with your post, but not everyone is willing to self-host or is capable of doing it. So I recommendation would be and one that I’m currently using, is when uploading a file to these cloud services encrypt your files. I’m using #cryptomator, but I’m sure there are other alternatives, like #rclone. There is also #veracrypt, but to my understanding, is not great for cloud sync.

Quick youtube video in how to use cryptomator (3:51)
Cryptomator is open source and free, but only on desktop. To use the mobile version, you will have to pay. Here is a list of alternatives to cryptomator, if you are familiar with one, please share your knowledge.
@Rodeo I’ve been using #piped as my alternative front-end to #youtube for like a year, and it’s working fine. I don’t use the official instance though; however, I did notice that the API was down for a couple of days (at least the subscription feed).
You can choose one from their instance list. Obviously, you are putting your trust to the instance owner.
