Linux only, SSH works fine. Not e2ee. Nextcloud works fine but extra work unless you use a service provider. It can be e2ee but not normally so. Syncthing worth a look too. It is not cloud storage, but direct device transfer. Bitwarden send is useful too if you want to juat send file someone, and thunderbird is working on thunderbird send which might be interesting.

Maybe Synology if you want your own lan NAS?

All email services have vendor lock-in unless your using your own domain.

For what it is worth, I just moved my mail from my ISP to my own domain at a hosting service after 30 years. Took about 5 months to get everything changed but if I can do it anyone can.

Downside, using your own domain is probably less private but kind of depends.

In project management lore there is the tripple constraint: time, money, freatures. But there is another insidious dimension not talked about. That is risk.

The natural progession in a business if there is no push back is that management wants every feature under the sun, now, and for no money. So the project team does the only thing it can do, increase risk.

The memory leak thing is an example of risk. It is also an example of some combination of poor project management including insufficient push back against management insanity and bad business mangement in general which might be an even bigger problem.

My point, this is a common natural path of things but it does not have to always be tolerated.

I get your point but I do not think you should justify releasing crap code because you think it has minimal impack on the customer. A memory leak is a bug and just should not be there.
