I feel very frustrated when I hear this argument, as if it’s futile to switch to a different email provider. It’s actually hyperbole. Most people use chat and messaging platforms (or social media platforms) to communicate with others. Personal email, IME, has reduced drastically over the years. That leaves emails that businesses send to individuals, which are usually sent through non-free-profiling-based-Gmail methods (including GSuite, which Google cannot use to profile people). Only small businesses that don’t know any better or don’t want to spend money on email would use an @gmail address (or @yahoo, @outlook, etc.) to correspond with potential and current customers.
