Having others run a service for you is a good thing! I'd love to pay a subscription for a service, but ran as a cooperative, where I'm not actually just paying a subscription fee, instead I'm a member and I get to decide what gets done as well.
This model works so well for housing, where the renters are also the owners of the building. Incentives are aligned perfectly, rents are kept low, the building is kept intact, no unnecessary expensive stuff added. And most importantly, no worries of the building ever getting sold and things going south. That's what I would like for my cloud storage, e-mail etc.
What you're describing is possible but you would need to market it differently if selling to non-tech people.
Now if you could make something like this https://oxide.computer/ for home users and make it affordable, that would be cool.
Also I am currently only targeting locals so I can physically go to their place and configure their server.
I don’t mind growing slowly here btw. It’s my side business and I plan to keep my current job for the time being.
