Privacy-friendly cloud storage with WebDAV and family plan support

I like onedrive a lot as it meets everything i need. But there is one issue. Privacy.

So i am using infomaniak kdrive right now. A very good one drive alternative if you like your privacy. But they keep having issues with payments. So i am looking for something else.

My partner and i are looking for a family plan. about 1tb per user. Webdev is very important for me as i always use nextcloud als a sync app. It is nice it has web office build in too just like onedrive has. as i have a lot of meetings.

Recently we purchased a family plan with internxt. But god their software is bad. So that is a no go.

I couple things we looking at

sync.com - filen - pcloud - icedrive

proton is a good one too. Bit a bit on the pricey side.

We are still doing research on pcloud as i still do not trust pcloud that well.. I dont know but something still smells about this company...

Anyone any ideas?
