Re: WAG
Meh.
When I got my Fairphone4 and installed /e/OS on it, I was looking for a de-googled, cloud-free phone with a micro-SD card for voluminous local storage, that I could back up myself via Syncthing.
Naturally, I didn't subscribe to a Murena account or use any of their cloud services, what would be the point? Someone else's computer etc.
So, I think the mistake was to bother offering these "services" in the first place. I don't want them, I don't know why anyone else would want them, and I don't know why they were offered in the first place.
Maybe, anyone who makes a mobile phone OS that gains any sort of traction soon gets a visit from some men in suits and dark glasses, who tell them that they must offer some cloud storage services.
