Let me be clear: we plan to charge a subscription. That's our only business model.
I think we can improve privacy and security for most users who have trouble managing it. For instance, we can patch Chrome zero-days (many have occurred this year) a lot faster for everyone.
What we offer today is a faster way to use applications that do own your data so you can be much more productive and hopefully enable a new set of applications never before possible.
We help improve decentralization of the web over duopolies like Apple/Windows. We make the browser more powerful, not less.
We improve the market share of Linux as a consumer computing OS as it underlies our tech.
In time, we might be open to people owning their own hardware and running Mighty on it but I think a lot of people will prefer we make it "just work" for now. I don't view either world as mutually exclusive.
If there's an opportunity to research making things trustless, we'll work on that.
