People love to smugly suggest this useless advice like there aren’t literal public services from governments around the world that are being tied to these platforms, let alone the many private companies which gate access to their goods and services behind apps on proprietary devices.

To say nothing of the fact that well-adjusted humans need to communicate with friends and family, and many times that also practically requires being on these platforms as well.

If it was be that simple. In that case I would have to go to the bank for every transaction/payment I want to initiate online. Banking app doesn't work for jailbroken devices. Using PC to access banks website works, but transactions still require 2FA and they don't support any other 2FA flow except the one in the app.

Or Microsoft.

Stay as far away from BigIT as you can. Linux or BSD are there for many good reasons. This is another one.
