There is no more than 100% wrong. Saying it is 1000% wrong implies that you are arguing emotionally, not rationally.
Rationally, it doesn't matter how google reacts to their non-customers. There is no obligation to treat them well. The correct approach for non-customers is to either become a customer or to switch to another provider.
If somebody is wrong it is the non-customers who could fix the situation. Their unwillingness to change email providers is what enables google to keep on providing that bad service.
It means I was employing the common rhetorical device of exaggeration.
