A possible counter argument could be that other customers don't use the services you do use and in the end it all evens out, but you'd need to look at the data to know if that actually is true. Perhaps if the all-in package has become less interesting for you and you could downgrade your membership to only get premium vpn or mail.
But that aside, i totally agree the vision of the leadership only makes sense if it is based on the needs of customers and I also doubt whether they are Protons main interest.
