I've tried and failed. I've been with Gmail since day one and I'm too deep to change every address. It'll never go away. I even use DDG but keep going back to Google & Bing when I'm dissatisfied. Google Drive is better than Duplicity and Carbonite, and way easier than OneDrive. Google Voice has no competition.
"Google Drive is better than Duplicity and Carbonite"
This is an odd sentence because Carbonite is a provider and Duplicity is a backup software that you can point at many different providers.
So Google Drive might indeed be superior to Carbonite but that has nothing to do with Duplicity.
Further, there is almost universal consensus that borg is superior to duplicity. It has been called the "Holy Grail" of backups[1].
What you should probably be doing is:
1) using 'rclone' to move data between clouds[2] - either downloading it back to yourself or migrating it to a new cloud that you prefer.
2) using 'borg' to initiate, or replace, existing backups with encrypted backups that only you hold the key to.
As you may know, there is a cloud storage provider with this half-page privacy policy[3] that explicitly supports both borg and rclone[4] and has those tools built into their environment.
I put them all together because the end goal is to provide some kind of backup strategy. In that context, all three are equivalent. (Carbonite has clunky FileManager-like GUI for handling backups.) Make sense now?
I actually use Google Drive for files I share with people who don't have MS Office, then I use Duply+PGP->Duplicity to AWS S3 backups of all documents on my Mac that aren't on GitHub (and don't have GB of object or docker files), and lastly I do monthly TimeMachine for the entire DISK (because TimeMachine is effing amazing, I won't go into to much detail, but it is brilliant when moving to a new machine).
When it comes to backups, I am reluctant to spin up rclone/borg when a single alias that calls Duply+PGP to S3 on my 1GBit upstream fiber has worked fine for almost 10 years. Just telling me I should switch to something without a making an effort to explain WHY is basically asking me to spend hours studying and trying something that might fuck up my established protocol for what ROI? I don't quite share your enthusiasm for new flows, prima fascie. ;-)
