The only way to make money, true money is through text subscription plans

Where the company sends out a text and unless the end user responds "No" or "Stop" they are signed up to the subscription.

This is in all forms a SCAM but is legal and supported by all phone services.

Supported to the point of when you call to have this removed, they will send you on a month long journey and still not have the issue resolved. Reason... A Portion of the subscription is paid to the cellular company for processing.

I do know of a few class action suits about to open up on this service and would be in the wrong by not stating "Stay away from this option"

The main thing is most people just pay a bill instead of looking at their line items. And some places list their company subscription service as (example) "Mantenance" - a typo to something you would see on a bill.
