Proton Drive? I am skeptical about this one. I know Proton is more secure on paper. But it is like going from 1 walled garden to another.

I use Proton for a few services and I think this is an unfair comparison, while you're right to be sceptical and Proton aren't perfect, they're much better than Google.
You need to move to a service that you can egress easy and proton does allow that.
