Something to keep in mind if you plan on moving to one of the alternatives that don't involve that creepy oversight by Apple or Google will be all the services and such that will become your own responsibility to maintain or pay for -- i.e. Google include at least 15GB of online storage for free with each user account, and that includes email, calendar, contact service, and more also free. If you want to maintain your own email server, just be aware it's not a trivial task and will involve regular maintenance, or if you want to move to a privacy-focused service like ProtonMail than you'll be paying $48 for 5GB of online storage (free ProtonMail includes just 500MB). So yeah, with Google we 'pay' by allowing it to data mine our personal info but if you, say move to a PinePhone to escape the Google-verse, you need to access all the Google services you rely upon now and what you need to implement when you don't.
