@stefano Oh, agreed. Even as a tech pro it's not easy. Earlier this year I started the process to de-Google. Not easy by any stretch of the imagination. It isn't so much dealing with Google's walled garden but the fact it's tech is integrated into so many other providers.
While I've moved my mail to a new and more ethical provider, I still have 566GB of stuff sitting in my Google Drive. While my new provider offers encrypted cloud storage, it is still *someone else's* data center. Though, it does inspire some confidence knowing they aren't a part of the NSA's PRISM Program.
There are other products I use which, upon registration, I used my Google account...which is also tied to my Android phone and TV.
Oh, and there's also Google Voice which I use for a variety of things including voicemail across my devices.
Given how tightly integrated companies are to Google (and/or other #bigtech players), it seems the only way to not be tangled in their thorn bushes is to never enter that garden. Ever.
