This should be seen as a encouraging to switch to something else rather than defeatist. Many of my communications do not touch Google services, professionally it has been judged as too risky, personally I keep a google account but also others.

Edit: You can create groups of people that are not affected by Google/Apple/Facebook, this should be seen as a goal.

This could be an interesting take, GDPR wise. Google handling personal emails of people that have no contract or business relationship with Google.
