My email address is linked to several hundred accounts which I use to run my life, manage my household, do finances, etc.
My email address is, of course, the primary means of communicating with me other than phone.
YouTube is my primary means of entertainment, but that's disposable.
I also use Sign In With Google on dozens of the above accounts, so they are a definite dependency on the Google account.
I own an Android phone and a Chromebook. I operate 3 personal accounts, and my employer relies on Google as our primary business platform.
My Google Calendar and Tasks are my sole method of scheduling everything I do in life, from daily tasks to events I attend and everyone's birthdays.
My Google Contacts contain all contacts of everyone I know and is the sole repository of that data.
Google Docs and Sheets are my sole word processing and spreadsheet apps, which I use to great effect for writing letters, managing household, etc. etc. I know them like the back of my hand, and I also use them every day for work.
All the photos I've ever taken since 2015 are stored only in Photos. Not many, of course, but some I'd miss.
I'm increasingly using Wallet and GPay for financial transactions and event tickets. I even hear tell that my jurisdiction is putting driver licenses on Wallet now.
So could you rephrase your advice to me please? Which $20/year service replaces these apps, and permits easy import of all my data from Takeout?
If someone used 365, would you demand that they GTFO Microsoft and junk their Windows systems? What should we run? A PDP-11?
