I've been using Google as my main mail service since 2006, and every single account or service I've ever signed up for was made with that address. For a long time I thought it'd be impossible to divorce myself from Google.
It took less than 5 minutes to switch to a ProtonMail account, less than 2 hours to download and/or offload every byte of data from my Google account, and less than 3 days to change every single account or service I've ever signed up for to the new address.
As of today, the only single one I have that's still tied to it is YouTube. It's the only thing I'd lose access to if I deleted my Google acount entirely.
They really, really want you to believe that it's a hassle to switch to a different email system. But it's not. Most websites and/or services allow you to change the email address associated with it.
I've been using Google for almost 2 decades and it only took a few days to move everything. It's not a painful sacrifice; it's an easy change that, frankly, has absolutely been worth it.
