Lots of companies have been forced to do provide free services to non-customers; consider almost any industry classified as a 'utility'.

Since when is any utility service free? Electricity, water, phone service. All of these require payment for service. For electricity you have to pay for both generation (from your chosen generator) and for transmission on the wires to your house. For water you have to pay for all water and sewage service to your house. For phone service you have to pay your provider. If you roam outside of their network they have to pay the other network to carry your traffic (and then it’s up to your provider to decide how to charge you for roaming).

Edit: I should add that email is an example of a service which is not a utility. Why? Email providers are free to block any message they like, preventing delivery in either direction. They typically use this discretion to filter spam but they're under no obligation to deliver. Anyone who has set up their own email server will know what I'm talking about: you have to jump through a lot of hoops to get your emails delivered to Gmail users!
