I’ve been thinking about this. I really think there can be zero trust. The last 30 years of experience have shown that there is no “cloud” that will ever be invulnerable to hacking/back doors/government subpoena.
I believe the future requires open source tools that allows everything to work together on your own hardware seamlessly. Anything else will 100% be taken and used against your will.
I would say the difference is only skin deep.
