If you’re fed up with companies fucking you over there’s an alternative.
There software called Nextcloud which you can run on a server which works in comparable ways as Onedrive/Google Drive/Dropbox/etc. works.
You could host it yourself on a server if you know how.
If you’re not familiar with forwarding ports or setting static IP adresses you can rent some server space from Hetzner where Nextcloud is included.

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.

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.
If it’s not open source and self hosted, I think it will probably turn out just the same as Dropbox. It’s the power dynamic. Closed SaaS, on someone else’s computers, is a very weak position. Not surprising when the relationship turns abusive.
